A piston cylinder contains 1.25 kg water at 25°C with a constant load on the piston such that the pressure is 300 kPa. A nozzle in a line to the cylinder is opened to enable flow to the outside atmosphere at 100 kPa and 25°C. The process continues until 85% of the initial mass has flowed out. At this point, the temperature of water increased by 10°C. Assume that the process is done in an Water isobaric manner. Write the mass and energy balance equations and calculate the work (kJ) and heat (kJ) involved in the process if the exit velocity is 40 m/s. For compressed liquid, assume the substance is a saturated liquid at the given temnerature

A piston cylinder contains 1.25 kg water at 25°C with a constant load on the
piston such that the pressure is 300 kPa. A nozzle in a line to the cylinder is
opened to enable flow to the outside atmosphere at 100 kPa and 25°C. The
process continues until 85% of the initial mass has flowed out. At this point, the
temperature of water increased by 10°C. Assume that the process is done in an
Water
isobaric manner. Write the mass and energy balance equations and calculate
the work (kJ) and heat (kJ) involved in the process if the exit velocity is 40 m/s.
For compressed liquid, assume the substance is a saturated liquid at the given
temperature.
