The inner diameter for a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k is 1.45 m
<h3>What is Stack Height ?</h3>
Stack height means the distance from the ground-level elevation at the base of the stack to the crown of the stack.
If a stack arises from a building or other structure, the ground-level elevation of that building or structure will be used as the base elevation of the stack.
Given is a steel stack that exhausts 1,200 cu.m/min of gases
P= 1 atm and
T= 400 K
maximum expected wind speed at stack height of 12 m/s
The formula for the diameter of chimney
Q =1200 cu.m/min
= 1200 * 0.0166 = 19.92 cu.m/sec
Velocity = 12m/s
d= 1.45 m
Therefore The inner diameter for a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k is 1.45 m.

Answer:
the equilibrium constant is 1.8 x 10⁻5 and strongly favor the reactants.
Explanation:
the chemical reaction provided for the two equation are the same but different direction i.e a reversible reaction. Assuming, the mass of reactants and product and temperature remain constant.
therefore, the equilibrium constant K, is 1.8 x 10⁻5. this is a very small value of K, thereby strongly favor the backward direction to form reactant.
Answer:
Element
Explanation:
An element is substance that is composed of only one kind of atom and can not be separated into simpler substances or converted into another substance by chemical processes.
Chemical elements are found in the periodic table. Examples of chemical elements include; sodium potassium, phosphorus, hydrogen etc.
Answer:
True.
Explanation:
Specific heat is the amount of heat required to raise one gram of a particular substance by one degree Celsius or Kelvin.
Formula for calculating specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.
= m * Cp * delta T
