Chapter 6, Problem 6.58P

Two rigid tanks are filled with water. Tank A is 0.2 m³ at 100 kPa, 150°C and tank B is 0.3 m³ at saturated vapor 300 kPa. The tanks are connected by a pipe with a closed valve. We open the valve and let all the water come to a single uniform state while we transfer enough heat to have a final pressure of 300 kPa. Give the two property values that determine the final state and find the heat transfer. B A

i need the answer quickly

3kg of Co2 expanded in a stationary piston cylinder through a polytropic process from 30 degree Celsius and 250 kpa to 100kPa pressure. If the polytropic exponent, n = 1.45, find the total work, total heat transferred, total kinetic energy change and internal energy change

A cycle HE does 60kJ of work per cycle. If the efficiency of the heat engine is 60%. The heat rejected per cycle is.

150 kJ of work is done in a rigid container while the internal energy increases by 95 kJ. Find the heat transfer, in kJ.

Please don't provide handwritten solution .....

I can't Figure out this? 1.83 Wrong.

I need a copyable tyepd answer which I can copy it

Q4: A 600 MW heat engine, which is cooled by water, the thermal efficiency of engine is 0.15 heat reject in engine. Determine the
