A storage tank for concentrated nitric acid will be constructed from aluminum to resist corrosion. The tank is to have an inside diameter of 6 m and a height of 17 m. The maximum liquid level in the tank will be at 16 m. Estimate the plate thickness required at the base of the tank. Take the allowable design stress for aluminum as 90 /^2.

Answers

Answer 1

Answer: P = ρ x g x H

Explanation:Where

ρ = density of water = 1000kg/m³

H = Height of the tank = 10m

g = acceleration due to gravity = 9.81m/s²

Substituting these values into   -----     Eqn 1    gives  

P = 9.81 x 10⁴Pa

Now for cylindrical shaped vessel,

The Longitudinal stress σ1 = P x r / 2 x t

where t= tank thickness = 10mm = 0.01m

r = tank radius = 2m

substituting these values into eqn2 gives

σ1 = 9.8 x 10⁶Pa

But from the mohr's circle stress analysis, we have

The maximum normal stress σm = σ1m = 2 x 9.8 x 10⁶Pa = 19.6MPa

The maximum shear stress σ1s = 9.8 x 10⁶Pa = 9.8Mpa

What are the four stages of gene expression?

Answers

Regulatory stages of gene expression Chromatin, chromatin remodeling, chromatin domains. transcription. Post-transcriptional modification. RNA transport.

Gene expression is regulated in eukaryotic cells at epigenetic, transcriptional, post-transcriptional, translational and post-translational levels. Environmental factors such as diet, temperature, oxygen levels, humidity, light cycle and the presence of mutagens all affect the genes expressed in animals and ultimately affect the animal's phenotype. Thus, during the expression of protein-coding genes, information flows from DNA → RNA → protein. This directed flow of information is known as the central dogma of molecular biology. A promoter is a region of DNA within 1-2 kilobases (kb) of the transcription start site (TSS) of a gene.

what are the differences between stiffness (i.e., elastic modulus) and resistance to fracture (i.e., fracture toughness) values at room temperature for metals, ceramics, and polymers? which group of materials is higher or lower for which property? explain.

Answers

Stiffness, or elastic modulus, is a measure of how resistant a material is to elastic deformation when a force is applied. It is generally higher for metals than for polymers and ceramics.

Resistance to fracture, or fracture toughness, is a measure of how resistant a material is to fracture or breakage when a force is applied. Generally, ceramics are higher than metals and polymers in terms of resistance to fracture. Polymers are the lowest of the three in terms of both stiffness and resistance to fracture.

In general, metals have the highest stiffness, and ceramics have the highest resistance to fracture, while polymers are lower for both properties. This is because metals are usually composed of strong metallic bonds, which help them resist deformation, while ceramics are usually composed of strong ionic bonds, which help them resist fracture. Polymers, on the other hand, are usually composed of weaker covalent bonds, which make them less resistant to both deformation and fracture.

how does the velocity of streamflow change where a stream channel becomes wider but the discharge remains constant?

Answers

The velocity drops when a stream channel widens while the discharge stays constant.

The water in a stream moves at a certain speed. Distance and time are units (e.g., metres per second or feet per second). The stream's velocity is highest midstream, discharge close to the surface, and slowest along the bed and banks of the stream because of friction.

The ratio of cross-sectional area to wetted perimeter is known as the hydraulic radius, or HR or simply R. The cross-sectional area is equal to the width times the depth (W * D) for a hypothetical stream with a rectangular cross section (a stream with a flat bottom and vertical sides). The wetted perimeter for the same hypothetical stream would be calculated as follows: W + 2D = Depth + Width + Depth.

An ice skater is gliding horizontally across the ice with an initial velocity of +6.94 m/s. The coefficient of kinetic friction between the ice and the skate blades is 0.0801, and air resistance is negligible. How much time elapses before her velocity is reduced to +2.92 m/s?

Answers

The time elapses before her velocity is reduced to +2.92 m/s is 5.5 seconds.

How to calculate time elapses?

v = the initial velocity = 6.94 m/s

v0 = the reduced velocity = 2.92 m/s

μ =  the coefficient of kinetic friction = 0.0801

g = the gravity = 9.8 m/s^2 (assumed)

First we calculate the acceleration of the ice skater with this formula,

a = μ*g

= 0.0801 * 9.8 = 0.78498 m/s^2

Then, from basic formula about velocity, acceleration, and time which is,

a = (v-v0)/t

We can change the formula to calculate time. So,

t = (v-v0)/a

= (6.94-2.92)/0.78498

= 5.5 s

Thus, time needed to reduce velocity to +2.92 m/s is 5.5 seconds.

To calculate the average cost, divide the total purchase amount by the number of shares purchased to figure the average cost per share.

The average cost share method is commonly used by investors for mutual fund tax reporting.

Therefore average cost per share = Total cost/ total share owned.For example, an investor that has $1000in an investment and owns 500 shares would have an average cost basis of $2 i.e ($10,00 / 500).

Similarly,The total cost =$ 2.80+ $1.90 = $4.70

The total share owned = 500+ 1000 = 1500

if a two-position solenoid-operated valve has only one solenoid, a(n) is used to return the spool to the de-energized position.

Answers

A spring-return actuator is a type of solenoid-operated valve that uses a spring to return the valve spool to the de-energized position when the solenoid is de-energized. This is useful in applications where the valve needs to be in the off position when no power is supplied to the solenoid, such as in safety systems. The spring-return actuator ensures that the valve returns to the off position even if the power is lost, ensuring that the system remains safe.

Understanding the Role of Spring-Return Actuators in Two-Position Solenoid-Operated Valves

In industrial and commercial settings, two-position solenoid-operated valves are designed to control the flow of liquids and gases. These valves are typically actuated by an electric current supplied to the solenoid, which energizes the valve actuator and moves the valve spool to the desired position. However, if a two-position solenoid-operated valve has only one solenoid, a spring-return actuator is used to return the spool to the de-energized position. This essay will explain the role of spring-return actuators in two-position solenoid-operated valves and how they help ensure the safe and efficient operation of the valve.

A spring-return actuator is a device that uses a spring-loaded mechanism to return the valve spool to the de-energized position once the electric current is removed from the solenoid. This ensures that the valve spool always returns to its default position when the electric current is switched off, thereby preventing the valve from becoming stuck in the open or closed position.

The one-inch device that Stephen Smith shows David Pogue has over a billion transistors, or tiny on-off switches.

A transistor is a tiny semiconductor that regulates or controls the flow of current or voltage in addition to producing, amplifying, and functioning as a switch or gate for these electrical signals. Three layers, or terminals, of a semiconductor material typically make up transistors. Each of these layers is capable of carrying a current.

A transistor changes a little input current into a larger output current while acting as an amplifier. To govern the flow of electronic signals through an electrical circuit or electronic device, it can be in one of two clearly defined states: on or off.

A semiconductor device known as a transistor can be used to conduct and insulate electric current or voltage.
