An irrigation pump draws water from a lake and delivers 25l/s to a jet nozzle at an elevated location 20m above the lake. the pipeline is 10cm diameter and has a loss coefficient of 30. the jet nozzle is 3cm diameter with a loss coefficient of 0.4 based on the jet velocity. the pump efficiency is 75% (a) what pump head is needed? (b) what power is needed to drive the pump?

An insulated tank truck containing 50,000 pounds of double-distilled, deionized water at 30 °c is pumped into a closed, refrigerated storage tank maintained at 5 °c in a facility located on top of mount mitchell, north carolina (elevation 6,684 feet & average july temperature of 84 °f). a)-determine the volume of the storage tank required to hold the purified water. b)- determine the initial and final pressure differences that must be overcome by a liquid pump assuming the storage tank initially contains air at 5 °c. assume the air is slowly bled out of the storage tank during the water transfer c.) during a routine operation today, the tank is slightly ruptured by a stainless steel pipe and a water acrosol of droplets begins to spray out of the storage tank. state all assumptions and determine the internal pressure within the water droplets produced
