Solution :
Using the data table for refrigerant-134a at P = 120 psia
∴
For pressure, P = 20 psia
Change in temperature,
Now we find the quality,
The final energy,
Change in internal energy
= 38.09297-40.5485
= -2.4556
Answer:
a) , b)
, c)
Explanation:
a) The tank can be modelled by the Principle of Mass Conservation:
The mass flow rate exiting the tank is:
b) An expression for the specific enthalpy at outlet is derived from the First Law of Thermodynamics:
Properties of water are obtained from tables:
The specific enthalpy at outlet is:
c) After a quick interpolation from data availables on water tables, the final temperature is:
Answer:
Explanation:
Sample output:
BANK ACCOUT PROGRAM!
----------------------------------
Enter the old balance: 1234.50
Enter the transactions now.
Enter an F for the transaction type when you are finished.
Transaction Type (D=deposit, W=withdrawal, F=finished): D
Amount: 568.34
Transaction Type (D=deposit, W=withdrawal, F=finished): W
Amount: 25.68
Transaction Type (D=deposit, W=withdrawal, F=finished): W
Amount: 167.40
Transaction Type (D=deposit, W=withdrawal, F=finished): F
Your ending balance is $1609.76
Program is ending
