LAST DIGIT IS 5, So P2 = 1.45

Major: Mechanical Engineering

 

Course: Thermodynamics

( Homework for students )

A piston-cylinder device initially contains 25 L of liquid water at 25 °C and 300 kPa. Heat is transferred to the water at constant pressure until the entire liquid is vaporized. Last one digit of your student number p2 (kg/m³) (a) What is the initial density of water? 1.70 (b) What is the final temperature? 1 1.65 2 1.60 (c) Show the process on a T-v diagram with respect to saturation lines. 3 1.55 (d) Provided that the initial properties of the water are at the same values, If 4 1.50 1.45 the density of the saturated vapor in final state is p2, calculate the work. You 6 1.40 can use the following table values for p2 7 1.35 8 1.30 9 1.25
