Pump head calculations?

A vacuum evaporator has a pressure of -76kpa Gauge. The evaporator level is 10 m above the center line of a pump. The pump discharges into a storage tank, located 20 above the pump. This tank has a level of 6 m and a pressure blanket of 100 kPa (gauge). Liquid velocities are 3 m/s in the suction piping and 4 m/s in... show more A vacuum evaporator has a pressure of -76kpa Gauge. The evaporator level is 10 m above the center line of a pump. The pump discharges into a storage tank, located 20 above the pump. This tank has a level of 6 m and a pressure blanket of 100 kPa (gauge). Liquid velocities are 3 m/s in the suction piping and 4 m/s in the discharge line. Friction loss in the suction line is 0.5 m and in the discharge line, 1.8 m. Calculate the pressure at inlet and the total dynamic head for the pump
