A 4 kg/s of saturated liquid water at 0.83 MPa is produced from mixing of cold water at 1.2 MPa, 0.001 m/kg and steam at 0.65 MPa, 160°C. Determine the required steam and cold water flow rates.

Saturated water at 36.6°C passes through a throttling valve and becomes a mixture of water and steam at 5.4°C. Calculate the specific volume and specific enthalpy of the mixture. Show detailed steps of how the properties are obtained by using only the Saturated Water and Steam table. Consider that a throttling process is a typical irreversible process. The specific enthalpies of the working fluid before and after a throttling valve are the same. The steam table has been provided in the image

An insulated rigid tank is div led into two equal parts by a partition. Initially, one part contains 5 kmol of an ideal gas at 25 kPa and 40°C, and the other side is evacuated. The partition is now removed, and the gas fills he entire tank. Determine the total entropy change during the process.

Moist air, saturated at 2°C, enters a heating coil at a rate of 10 m3/s. Air leaves the coil at 40°C. Find the required rate of heat addition. I NEED COMPLETE SOLUTION, PLEASE DONT USE PSYCHOMETRIC CHART. USE IT AS A CHECKING.

Propane initially at 300 K and 100 kPa is is compressed to 1 MPa in a reversible, steady-flow, and compressor. Determine the amount of work in kJ/kg if the process is isothermal. Round your answer to one decimal place
