Steam at 5 MPa and 600°C enters an insulated turbine operating at steady state and exits as saturated vapor at 50 kPa. Kinetic and potential energy effects are negligible. Determine
(a) the work developed by the turbine, in kJ per kg of steam flowing through the turbine.
(b) the isentropic turbine efficiency.
the crate containing 40 bricks sits on a slopped conveyor belt which is used to raise the crate to the next level of
An ideal Rankine cycle uses water as its working fluid. The mass flow rate of water through the cycle is 150 kg/s. saturated vapour enters the turbine at 15 MPa and saturated liquid enters the pump at 10 kPa. Cooling water passes through the condense..
What is the conductivity of silicon if As dopant is added to achieve a concentration of 1.0x10^23 atoms/m^3? let \mu _n =.14m^2/V-sec and \mu _p = .05m^2/ V-Sec
a barometer is used to measure atmospheric pressure contains mercury with a density of 13590 kgm3. if the local
An equimolar mixture of helium and argon gases is to be used as the working fluid in a closed-loop gas-turbine cycle. The mixture enters the turbine at 2.5 MPa and 1300 K and expands isentropically to a pressure of 200 kPa. Determine the work outp..
