Liquid benzene at 38^oC  with a vapor pressure of 26.4 kN/m² and a density of 860 kg/m³  is to be pumped at a rate of 0.0025 m³/s from a storage tank to a  discharge location 3 m above the liquid level in the tank. The pump with a  mechanical efficiency of 60 percent is 1 m above the liquid level. The storage  tank is at atmospheric pressure. The pressure at the end of the discharge line  is 445 kPa absolute. The inside diameter of the pipe used to transfer the  benzene is 0.0409 m. The frictional pressure drops in the suction and the  discharge line has been evaluated as 3.45 and 37.9 kN/m²,  respectively. Determine the head developed by the pump and the total power  requirement. If the pump manufacturer specifies a required net positive head of  3.0 m, will such a pump be applicable for this service?
