1. Isobutane gas and liquid mixture (x=0.9) is running through a valve to get 100% vapor condition and then entering the turbine to produce work. The conditions are shown in the figure. Isobutane mass flow rate is 10 kg/s. Valve 20 Power out Turbine P₁ = 17bar T₁ = 91.78 C P2 = 10 bar 3 P3= .08 bar T=20C Determine: a. The turbine inlet diameter is D2=0.05 meters. Determine the inlet velocity V2=? b. If the turbine work is 535 kW what would be turbine outlet velocity in m/s? Neglect heat transfer and potential energy. c. compute the turbine exit diameter d. Plot the diagram T-V showing all stages 1-2-3

Read the problem carefully and provide complete solutions with derivation of formulas (integrals and derivatives). Complete solution and units please. Use two decimal plaas for final answers only. 3 min 5. A time- stage compressor receives air at 100 ft³ at 10 psia and the discharge pressure is pressure is 200 psia. If the temperature of the air received is 50 F, find the intercooler pressure, total compresser work and total heat rejected at the intercoolers Answer: 44.72 psia, 16. 31 hp, Bty 345.80 min

I need help with some review problemsfor thermo! thank you  Air at 100 kPa and 280K is compressed steadily to 600 kPa and 400K in an air compressor. The mass flow rate of air through the compressor is 0.02 kg/s and the compressor a heat loss of 16 kJ/kg from the compressor occurs. Assuming steady state steady flow conditions and ideal gas behavior (with constant specific heats, Cp=1.009 kJ/kgK, R=0.287 kJ/kgK, determine: a)The necessary power input to the compressor (kW).b)The volumetric flow rate of air at the exit of the compressor (m3/s).

The steam rate to a turbine for variable output is controlled by a throttle valve in the inlet line.Steam is supplied to the throttle valve at 1,700 kPa and 225°C. During a test run, the pressure atthe turbine inlet is 1000 kPa, the exhaust steam at 10 kPa has a quality of 0.95, the steam flowrate is 0.5 kg/s, and the power output of the turbine is 180kW. 1. What are the heat losses from the turbine? 2. What would be the power output if the steam supplied to the throttle valve were expandedisentropically to the final pressure?

Finding exit temperature in F, and volumetric flow rate. Step by step solution please thank youuu

Solve the following problem and show your complete solutions for better understanding.

Air with a pressure of 0.1 MPa and a temperature of 25oC with a flow rate of 5.29 kg/minute enters a three-stage reciprocating piston compressor with intercooler. The air is compressed polytropically (n = 1.3) to reach the pressure of 4 MPa. Calculate: a) The pressure at stage-2 and stage-3 so that the compression work is minimum? b) The compression work in each stage and the total compression work? c) The outlet air temperature from each stage's cylinder? d) The amount of heat transferred to each intercooler? e) How much air is needed for cooling in the intercooler if the allowable maximum temperature changes between the inlet and outlet of the intercooler is 8oC?

could you help me with this problem

Answer the problem correctly and provide complete and readable solutions. If you can explain the process (briefly), please do so. Thank you!

For air properties use online source: https://www.peacesoftware.de/einigewerte/luft_e.html  The compressor is operating at steady-state increasing pressure of R-22 refrigerant from 4 bars to 14 bars. Temperature was rising during the process from 12C to 90C. The inlet volumetric flow rate is 1 m3/min and inlet diameter is 0.03m. At the exit the diameter is the same. Heat flow to the surroundings can be neglected. Determine: a.Mass flow rate [kg/s] b. Inlet and outlet velocity [m/s]                            c.Power required to run the compressor [kW]
