The primary winding of a 220'6 v, 50 hz transformer is energized from 110 v, 50 hz supply. the secondary output voltage will be: a)- 3.6v b)- 2.5 v c)- 3.0v d)-8v

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
