Question

A closed rigid tank contains water initially at 10,000 kPa and 520ºC and is cooled to a final temperature of 270° C. Determine the final pressure of the water.

Answer 1

final pressure is 6847.41 kPa

Step-by-step explanation:

given data:

`P_1 =  10,000 kPa`

`T_1 =520\ degree\ celcius = 793 K`

`T_2  = 270 degree celcius = 543 K`

as we can see all temperature are more than 100 degree, it mean this condition is refered to superheated stream

for ischoric process we know that

`(P_1)/(T_1) =(P_2)/(T_2)`

`(10*10^6)/(793) = (P_2)/(543)`

`P_2 = 6.84741*10^6 Pa`

final pressure is 6847.41 kPa
