Water in a piston–cylinder assembly, initially at a temperature of 99.638c and a quality of 65%, is heated at constant pressure to a temperature of 2008c. if the work during the process is 1300 kj, determine (a) the mass of water, in kg, and (b) the heat transfer, in kj. changes in kinetic and potential energy are negligible.

1) what is the power in horsepower of a 100 watt light bulb? what is the power in kilowatts of a 200 horsepower engine? 2) if a cars engine is providing 3000 n of force to keep the car moving at 5 m/s, what is the engine’s effective power? 3) how many gallons of water will be pumped from a well 30 feet deep by a 1/2 hp engine in 1 minute? (1 gallon weighs 8.34 pounds)
