A pump is to be placed $0\mathrm{.}1$m above the ground. Determine the head that the pump needs to produce in order to deliver water at $425$kpa, $4\mathrm{.}05$m above the outlet of the pump at a flow rate of at least $750$ liters$/$min at a temp of $70$ degrees C$.$ The water in the tank is at $0$ psig. It travels $2$m horizontally before reaching the pump, which is $0\mathrm{.}25$m wide. The water then travels another meter before going through a $90$ degree elbow and travelling $4\mathrm{.}05$m vertically before going through another $90$ degree elbow to the gauge measuring the pressure as $425$kpa. Determine the relative roughness for the pipe $($$/$D$)$ as well. Assume the kL for the $90$ degree elbows is $0\mathrm{.}3$
