Your client also proposes to use a flow nozzle to measure the flow. For a nozzle diameter to pipe diameter ratio of $0\mathrm{.}5$: $$ What is the pressure drop across the nozzle? $$ With this addition to the system $($which is an additional energy loss$),$ by how much $($show it in percentage$)$ would the pump power increase? Please note that the equation for pressure drop you derived for the $1$st question is the total pressure drop that includes the pressure drop due to the fluid acceleration and the pressure drop due to energy losses. To get the portion of the energy loss use this equation: NEXT FIND THIS For a good working system, the amount of pumped water should not be too much to dry the lower open channel. The company wants to know whether the amount of pumped water is negligible compared to the total flow rate running through the lower open channel. Please note that this is a natural channel with light brush and its average slope is $0\mathrm{.}00015.$ Compute the flow rate running through the lower open channel. $$ Compute the percentage of pumped water flow with respect to the lower open channel flow. Only show me for $4$ft I need to repeat for from $4$ ft to $8$ ft to find the corresponding percentage of pumped water flow.
