What should be the pressure indicated by the manometer at point 1, if the efficiency of the pump is 90%? The tank shown is open to atmosphere. The piping used in the system is Schedule 40 stainless steel. Consider a height difference of 8 meters between the storage tank and the manometer. Note: In all cases use soft flanged elbows.
