A simple U-tube manometer is installed across an orifice meter. the manometer is filled with mercury(specific gravity 13.6), and the liquid above the mercury is carbon tetrachloride (specific gravity 1.6). the manometer reads 200nm. what is the pressure difference over the manometer in newtons per meter?
Refrigerant R-134a vapor in a piston-cylinder assembly undergoes a constant-pressure process from saturated vapor at 800 kPa to 50 ºC.
Water is being pumped from a large lake to a reservoir 30 m above at a rate of 5x10-3 m3/s by a 12 kW (shaft) pump. If the irreversible head loss of the piping system is 8m, determine the mechanical efficiency of the pump.
