# thermodynamic phase problem

## thermodynamic phase problem

(OP)
An experiment requires supplying a reactor with ammonia. One of the proposed solutions is to provide ammonia from containers filled from the factory tanks. The volume of containers is 100 ft^3. The complete unloading and and filling cycle of the containers are as follows:
1. First the container is in storage A (temperature TA), where it remains for a long time. The proportion of ammonia in the gas phase is Y.
2. The container to be used is transferred from storage A and immediately connected to the reactor. During transport there is no heat transfer. The ammonia is leaving from the top of the container and the flow is stopped when the pressure in the vessel is P1. Because of the short duration,the experiment can be deemed as adiatherma.
3. The empty container is placed in store B (TB temperature), where it remains for a long time.
4. The container to be filled is transported from storage B in the compressor space, without significant heat flow lag. The filling is done by connecting the container in ammonia compressor. The ammonia flows adiatherma,with pressure P2 and temperature T2, until the pressure inside the container becomes equal to P2. Subsequently, the container is transferred to A and the cycle is repeated.

Determine the amount of ammonia remaining in the container after the 3rd evacuation.
Y=0.96
ΤΑ = 110
P1 = 125
P2 = 240
TB = 60
T2 = 120

(T in Fahrenheit
P in Psi-a)
if anyone can help me , i would apreciate it.

### RE: thermodynamic phase problem

We don't solve problems for you. Show us the work you've done so far and we can help lead you out of tough spots, but you have to do the work.
