Problem $5(25$ Points$)$

The following hydraulic systems is used to transfer

kerosene from Tank A to Tank B$.$

The total length of $2-$in NPS Sch $40$ steel pipe is $30$ feet

and the two $90$ bends are standard elbows.

Consider the major and minor energy losses and state

your assumptions.

$(15$ Points$)$ Calculate the pressure required above

the kerosene in tank $A$ in order to maintain

a flow rate of $130$ gpm into Tank B$.$

$(10$ Points$)$ Compute the minimum pressure required above the kerosene in tank A in order to

have flow between the two tanks. $($Hint: for hydrostatic conditions $h_L=0)$
