You mix together two flows of water. The first flow is a saturated liquid at 300 kPa, moving at a rate of 2 kg/s. The second flow is a superheated vapor at 300 kPa and 300 °C, and is moving at a rate of 0.2 kg/s. If the outlet is similarly at 300 kPa, (a) what is the mass flow rate of the outgoing water, (b) what is the temperature of the outgoing water, and (c) What is the rate of entropy generation for this process?

Saturated water vapor at 300°F enters a compressor operating at
steady state with a mass flow rate of 5 lb/s and is compressed
adiabatically to 750 lbf/in.2
If the power input is 2150 hp, determine for the compressor:
(a) the percent isentropic compressor efficiency and
(b) the rate of entropy production, in hp/°R.
Ignore kinetic and potential energy effects.

Liquid water at 15 ℃ is heated by mixing it with saturated steam
at the same pressure. Liquid water enters a chamber at a rate of
4.3 kg/s and saturated steam enters at a rate of 0.17 kg/s. The
mixture leaves the mixing chamber as a saturated liquid at 40℃. If
the surroundings are at 15℃, determine (a) the temperature of the
saturated steam entering the chamber, (b) the exergy destruction
during this mixing process, and (c) the second-law efficiency...

A mass of 5 kg of saturated liquid vapor mixture of water is
contained in a piston cylinder device at 100 kPa, initially 2 kg of
water is in the liquid phase and the rest is in the vapor
phase.Heat is now transferred to the water and the piston which is
resting on a set of stops, starts moving when the pressure in side
reaches 200 kPa, heat transfer continues until the total volume

Using Ees Program (With the Code and
Output)
Saturated liquid Propane flows in to a valve. It enters at 375
psia, and leaves at 15 psia. Mass flow through the valve is 1.25
lbm/hr. Use EES and ‘Propane’ as your fluid to calculate the
following:
The quality of the Propane exiting the valve
Temperature of the Propane exiting the valve (in °F)
The change in entropy of the Propane (in Btu/lbm-R)
