witti Steam at 5mPa and 500 C enters a nozzle steadily wit a velocity ef 80 m and it leaves at 2 MPa and 400°c. The indet area of the nozzle is 50 cm² and heat is being lost at a rate of 4e 90R%. determine the mass flow rate of the Steam, the exit velocity of the steam the exit area of the nozzle.

The valve connected to a 450-liter insulated tank of air at 250 kPa and 50̊C is opened,allowing the gas to escape until its pressure drops to 120 kPa. An electric heater insidethe tank maintains the temperature at 50̊C. Using variable specific heats, Determine thefollowing:a) The mass of air withdrawn (kg)b) The energy input to the resistor (kJ)

A mass flowrate of 1 Ibm/s of water at 80 F and 70 pisa is mixed with 1 Ibm/s of saturated vapor water at 70 psia in a mixing chamber. During this process 100 Btu/s of heat is lost from the mixing chamber to the surrounding environment. The exiting stream leaves the mixing chamber at 70 psia. In the question that follows, select the answer that is closest to the true value. What is the quality of the exiting stream ?

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
