4. Now assume that the house is built on the same level as the supply tank such that the surface of the water in the supply tank is level with the faucet in the bathtub. There would need to be a pump in the system to supply the energy to provide the same flow rate to the bathtub. The flow rate is the same so the friction losses and minor losses you just calculated for question 3 do not change. How big of a pump would I need to still provide the same flow rate into the bathtub
