A turbine agitator having six flat blades and a disk has a diameter of 0.203 m and is used in a tank having a diameters of 0.61 m. The width W=0,0405 m. Four baffles are used having a width of 0.051 m. The turbine operates at 275 rpm in a liquid having a density of 909 kg/m3 and viscosity of 0.020 Pa.s. Calculate the kW power of the turbine and kW.m3 of volume.

1. If wind speed doubles, the power output of the turbine will increase by a) 8 times b) 4 times c) 2 times d) 6 times 2. The wind speed at which maximum output power is generated by a wind turbine is called as a) Maximum wind speed b) Cut out wind speed c) Rated wind speed d) Cut in wind speed

Work is produced during a steam power plant cycle by the following equipment/step(s) (SELECT ALL that apply): Condenser Boiler Pump Turbine/Expander

A submersible pump at the bottom of an underground tank lifts water to an overhead tank.The underground tank is 2 m below the surface while the overheadtank is 4 m above the surface. What is the minimum impeller size that the pump should have if all the available motors rotate at 1800 rpm?

A gas turbine power plant with the following specifications: two axial compressor stages, the pressure ratio is 6/1 for each compressor. The inlet and exit angles of both moving and fixed blades are 40° and 20° respectively, the work done factor is 0.82, six stages for each compressor. intercooling between stages. A high pressure turbine is used to drive the compressors, and a low pressure turbine drives the generator. The temperature of the gases at entry to the high pressure turbine is 600°C and the gases are reheated to 700°C after expansion in the first turbine. The exhaust gases leaving the low pressure turbine are passed through a heat exchanger to heat the air leaving the high pressure stage compressor. The air inlet temperature to the unit is 20°C. The isentropic efficiency of each turbine stage is 0.95; the heat exchanger thermal ratio is 0.7. A mechanical loss is 5% for both the generator- turbine shaft and the compressor- turbine shaft. Assume any missed values to Calculate…
