Derive the equation of finding volume flow rate for Flow nozzle & Venturi meter

Provide a complete solution and answer for the given problem in the attached image.

Show in Figure 1 is the water flow system. The velocity head difference is  .  Volume flow rate is  .  The heights are   and  , respectively.  The power output from the motor is  ,  . The energy added by the pump is  . The energy loss between point 1 and 2 is  . 3)  Select the correct expression of the pressure head difference between point 1 and 2     ___________

. The type of flow in a tapering pipe or nozzle with constant velocity at the inletA. Steady Non-uniform C. Steady Uniform B. Unsteady Non-uniform D. Unsteady Uniform

Draw how it look if it is a laminar flow in pipe.

A 10,000-gallon water tank atop a building delivers fresh drinking water for itsoccupants. A top-floor resident and a bottom-floor resident are filling their bathtubs.Assuming frictionless pipes and isothermal flow, which one will fill faster?A. top floorB. bottom floorC. the tubs will fill at the same rateD. need more information
