and 80 m/s and at the exit it is 500 KPa, 40% quality and 30 m/s. The mass flow of the steam is 12 kg/s. a) With the power that comes out of the system, 252 100 W bulbs can be lit. Calculate the efficiency of the system. b) What is the area of ​​the duct at the entrance? c) What is the volumetric flow at the outlet? d) What is the temperature of the steam at the outlet?

Helium is compressed through a compressor steadily.  At the inlet the pressure is   and the temperature is  . At the exit the pressure is    and the temperature is  .  The power input is   and the heat loss rate is   during this process.  Neglect the kinetic and potential energy changes.  Assume helium is ideal gas with a constant specific heat   and its specific heat ratio  , which means that enthalpy can be calculated using  .  Calculate the work per unit mass   _________

Refrigerant R-134a at 200 kPa and 50 ⁰C enters an adiabatic diffuser steadily with a velocityof 140 m/s and leaves at 500 kPa and 150 ⁰C. Determine:  a) The exit velocityb) The inlet to exit area ratioc) The inlet exit density ratio    clear writing please

Sketch and label the nozzle. Sketch and label the process on a P-v diagram, also mention all numbers on the process of P-V diagram please. 7.15 The exit nozzle in a jet engine receives air at 1200 K, 150 kPa with negligible kinetic energy. The exit pressure is 80 kPa, and the process is reversible and adiabatic. Use constant specific heat at 300 K to find the exit velocity.

Butane enters an adiabatic compressor at 20psia and 250F with a volume Clow rate of 12ft3/s and leaves at a pressure of 130psia. The power output of the turbine is 55hp. Find a) mass flow rate of butane, b) the exit temperature.

I need help with a review porblem I cannot solve! thank you Steam enters an adiabatic turbine at 4 MPa, 800K and exits at 8 kPa, 90% quality. Assuming steady state, steady flow conditions, determine: a) The power output of the turbine (MW) if the mass flow rate is 63kg/s. b)The volumetric flow rate at the inlet (m3/s).

A steam pipe carrying 400C, 200kPa steam enters a well-insulated mixing chamber where it is mixed with a 30C, 200kPa stream of cold water with twice the mass flow. a) what is the enthalpy of the exit stream? b) what is the quality of the exit stream?

I have been working on this problem for a while but I need to figure out how to get the specific enthalpy when the refridgerant exits the system to find the mass flow rate of when the refridgerant exits the system but I don't know how to do this

Problem 4. Consider an adiabatic steam turbine operating at steady-state with a mass flow rate of 12 kg/s. At the inlet, the steam pressure is 10 MPa, the temperature is 450 °C, and the velocity is 80 m/s. At the exit, the pressure is 10 kPa, a quality of 0.92, and a velocity of 50 m/s. Find the change in kinetic energy Wout = ? Steam turbine (kJ/kg), the work out (power generated in MW), and the turbine inlet area (m²).

How do I do this questions in steps? Stuggling with how to find the isentropic work for the efficiency of the turbine. Please have written out or neat solutions that arent copied and pasted math.
