Apelton wheel nozzle, for which cy 0.97, is 400 m below the surface of a lake. the jet diameter is 80 mm, the pipe diameter is 0.6 m, its length is 4 km and f 0.032. the buckets deflect the jet through 165 and they run at 0.48 times the jet speed, bucket friction reducing the velocity at outlet by 15 percent of the relative velocíty at inlet. mechanical efficiency 90%. determine: a)-the flow rate b)-he shaft power developed by the turbine

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
