Thanks for the reply so, for saturated water at T=120 degress the Psat=0.1985MPa and v=0.001060m^3 given the mass of the saturated liquid is 0.50kg and the total volume of the piston is 0.10m3. So the air is taking up 0.09894m3 of volume. How can I link it to how much mass it is?Do I have to...
Homework Statement
Problem shown in attach picture
A cylinder of total internal volume 0.10 m3 has a
frictionless internal piston (of negligible mass and
thickness) which separates 0.50 kg of water below
the piston from air above it. Initially the water exists
as saturated liquid at...

ahh, I get it, so I do 5kw/.35= q in?
another question how could i calculate heat reject. It is process 3-4 in a carnot cycle which is isothermal heat rejection. If I apply First Law it wud be typically that q3-4 or qout= RT3*ln(v4/v3) but I can not get this volume , or should I be using...
n carnot = Wcycle / Qin
this would help me solve rate for power supply into system, given i know thermal efficency as .35 / 35% but I do not know the W cycle, I am only given the Work output which is 5KW. No volume is given so I can't go through the first law and calculate the total work for...
Homework Statement
An ideal Carnot engine produces a power output of 5kW at a thermal efficiency of 35% while rejecting heat reversibly to a reservoir at 30degrees. It achieves this output while executing 10 cycles per second.
a) What temperature is the engine receiving its heat supply...
