For a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k, calculate the inner diameter if you are designing for
bonufazy [111]

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

\rm d=\sqrt{\dfrac{4Q}{\pi v} }

Q =1200 cu.m/min

= 1200 * 0.0166 = 19.92 cu.m/sec

Velocity = 12m/s

\rm d=\sqrt{\dfrac{4\times 19.92}{3.14*12} }\\

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.

In which species does phosphorous have the highest oxidation number?
nignag [31]

the compounds in which phosphorous posses the highest possible oxidation have to mention here.

The species in which phosphorous have the highest oxidation state are: H₃PO₄, P₂O₅, PCl₅

The possible oxidation state of phosphorous is III and V. The highest oxidation state is V. There are several compounds in which phosphorous posses the +5 oxidation state. Like- Phosphoric acid (H₃PO₄), phosphorous pentoxide (P₂O₅), Phosphorous chloride (PCl₅) etc.

The oxidation state of an element depends upon the valence electron the valence shell of phosphorous is 3s² 3p³. Thus there are 5 electrons, as it has vacant 3d orbital thus it can easily form compound having +5 oxidation state.

how do different stimuli affect the survival behavior of an organism?THIS IS THE SECOND TIME IM ASKING PLZZZZ HELP ME
Anna35 [415]

Answer:

Organisms change their behavior in response to changes in the surrounding environment.

Explanation:

All living things can respond to stimuli in the exterier environment, It is a form of energy—light waves or sound vibrations, From what they sense they will make neccisary changes to their diet and or where they are located.

Such as winter weather which is a type of stimulus will cause some animals to start hibernating.
