6. Superheated steam at 1OMPa, 400°C is flow through an adiabatic nozzle of back pressure IMpa, and exit area of 10cm2. Find the Mass flow rate through the nozzle, the throat area that giveMaximum mass flow rat

A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350 °C and velocity of 15 m/s. The exit is at 100 kPa, 150 °C and very low velocity (assume zero). Find the specific work (kJ/kg) and the power (kW) produced.

Q2Air enters an insulated turbine at 50°C, and exits the turbine at - 30°C, 100 kPa.The isentropic turbine efficiency is 70% and T1=50C V=20L/s the inlet volumetric flow rate is 20 L/s. What is the turbine Air turbine inlet pressure and the turbine power output? T2=-30C.P2=100kpa

A complex flow system expands helium from 1500 K, 1000 kPa to 500 K, 100 kPa. In the process this produces 4595 kJ/kg of work. The process exchanges heat with a reservoir at TR. If the process is reversible, find the unknown reservoir temperature (K). You can work this with either Thermofluids or the equations... Your choice. If equations, Cp=5.19 kJ/kg-K, Cv=3.12 kJ/kg-K, R=2.08 kJ/kg-K. Helium 1500 K 1000 kPa TR q 500 K 100 kPa W=4595 kJ/kg

Q4:- A small dam has a pipe carrying liquid water at 150 kPa, 20°C with a flow rate of 2000 k in a 0.5 m diameter pipe. The pipe runs to the bottom of the dam 15 m lower into a turbinę w pipe diameter 0.35 m. Assume no friction or heat transfer in the pipe and find the pressure Pr ab turbine inlet. If the turbine exhausts to 100 kPa with negligible kinetic energy what is the rate of work? DAM 2 Turbine 3

can you write all steps ,and what you use (chart) be hurry please

A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350°C and velocity of 15 m/s. The exit is at 100 kPa, x = 1 and very low velocity. Find the specific work and the power produced.

5- Nitrogen gas flows into a convergent nozzle at 200 kPa, 400 K and very low velocity. It flows out of the nozzle at 100 kPa, 330 K. If the nozzle is insulated, find the exit velocity. a- 222 m/s b- 382 m/s c- 512 m/s d- 640 m/s AU-0 means that the process is isothermal?
