1.A smooth plastic garden hose 30 feet long is used to drain water from a pond into an open field. The hose has an inside diameter of 2 inches. If viscous effects are neglected (inviscid/frictionless flow) and the hose outlet is 10 feet below the surface of the pond, calculate the volumetric flow rate inside the hose in units of gallons per minute (gpm).
2.Draw and explain a pump curve that illustrates the effect of throttling in the CLOSED direction (i.e., reducing flow) the discharge valve for a constant speed centrifugal pump installed in a cooling water system.
