Determine approximately the degrees of superheat of a steam at 150 kPa and 7.3709 kJ/(kg-K).

Refrigerant-134a at 400 psia has a specific volume of 0.1384 ft3 /lbm. Determine the temperature of the refrigerant based on (a) the ideal-gas equation, (b) the generalized compressibility chart, and (c) the refrigerant tables.

A mass of 10 g of oxygen fill a weighted piston-cylinder device at 20 kPa and 94.0°C. The device is now cooled until the temperature is 0°C. Determine the change of the volume of the device during this cooling. The gas constant of oxygen is R = 0.2598 kPa.m³/kg-K. (Round the final answer to three decimal places.) The change of volume is m³.

Hello Sir,Good Morning.I have a question in my homework related thermodynamics lesson. The following below is my question. Please advice. Thank you. Regards,Irfan

Determine the mass of air in lbm when the pressure is 20.45 psi and the temperature is 77°F in a closed chamber with dimensions 30.8 ft x 15.3 ft x 17.8 ft. Assume air to be an ideal gas.

A coal fire boiler plant consumes 400 kg of coal per hour. The boiler evaporates 3200 kg of water at 44.5 degrees * C into superheated steam at a pressure of 12 bar and 274.5 degrees * C . If the calorific value of fuel is 32760 kJ/kg of coal. Determine equivalent evaporation from and at 100 degrees *C and the thermal efficiency of the boiler. Assume specific heat of superheated steam as 2.1 kJ/kg.K.

Determine the specific volume of superheated water vapor at 15.65 MPa and 355.11 C, using the generalized compressibility chart. Assume that the compressibility factor is 0.65. Round off your answer to 4 decimal places. R = 0.4615 kPa·m3/kg·K    Tcr = 647.1 K    Pcr = 22.06 MPa

Required information A piston-cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables. Determine the final temperature. (You must provide an answer before moving on to the next part.) The final temperature is °C.
