The owners of a luxurious mountain resort want to install a fancy water fountain. The artist’s initial design uses 75-m of 7.5-cm diameter commercial steel pipe ending in a nozzle with a diameter of 3.75-cm with a 40-kW pump to pull water from a lake above the resort at a flow rate of 0.05 m3/s. To save operating costs, the owners want to remove the pump and rely only on gravity head to power the fountain. Assuming the friction factor is 0.016 for both cases and neglecting minor losses, determine:
a. the flow rate if the pump is removed from the system (in m3/s)
b. the height of the water jet with and without the pump if the nozzle is pointed vertically up (in m).
