A piston-cylinder device contains 0.005 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 600 kPa. Heat is transferred at constant pressure until the temperature reaches 200°C.
(a) What is the initial temperature of the water?(b) Determine the total mass of the water.(c) Calculate the final volume.(d) Show the process on a P-v diagram with respect to saturation lines.
If the efficiency of the turbine in converting the mechanical energy given up by the fluid to the turbine shaft is 89% (nt = 0.89), calculate the friction loss in the turbine in J/kg.
What is the wear coefficient of the bearing material in m2N-1 ?
a) What is the temperature and state of the steam in the pipe? b) What is the quality of the steam in the pipe?
