A mass of 12kg of refrigerant-134a initially exists as a saturated vapor in a piston-cylinder device at 240 kPa. Then, 300kJ of heat is transfered to the refrigerant at a constant pressure while a 110-V source supplies 12.8 amps of current to a resistor within the cylnider for 6 minutes.
Determine the following:
a. The work provided by the electrical source
b. Specific enthalpy at the final state
c. Temperature of the initial state.
d. Description of the final state.
e. Temperature of the final state.
f. Show the process on a P-v diagram with respect to saturation lines.
g. Compute the boundry work.
