The discharge from an old sewer 400 m long when flowing full has been measured as 40 l/s. The pipe diameter is 200 mm and has an estimated surface roughness of 0.6 mm. Taking the kinematic viscosity as 1.0 mm/s, calculate the head loss in the pipe. (the non dimensional friction factor -0.02; g is taken as 9.81 m/s²)​

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody
