Question

4.31 Initially, an insulated rigid tank contains 3.12 kg of water at 270 celsius and 1 MPa.

A heater in the wall of the tank maintains the wall temperature at 600 celsius.

After a period of time, the pressure in the tamk rises to 1.5 MPa.

Determine the final temperature Celsius of the water in the tank.

Use specific heats from tables for water.

Answer: 524.37

PLEASE SHOW ALL WORK INTERPOLATION AND

HOW TO GET ALL NUMBERS NEEDED thankyou so much

Please use these tables and state which ones used thanks much

initial temperature of water is T1 = 270 oC

the initial pressure is P1 = 1 MPa = 1 x 10^6 Pa

let the final temperature be T2

the final pressure is P2 = 1.5 MPa = 1.5 x 10^6 Pa

we know that

P1/T1 = P2/T2

or T2 = (T1/P1) x P2
