Hydrogen at atmospheric pressure and at 80c flows over a flat plate with a velocity 3m/s. determine (a) the local drag coefficient at a distance of 2m from the leading edge, and (b) the average drag coefficient over a distance of 2.2m from the leading edge

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

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
