QUESTION $2$

$($a$)$ List two $(2)$ work$-$rate terms that have important effect in the derivation of the general energy equation.

$(1$ mark$)$

$($b$)$ A pump is used for a water fountain system as shown in Figure Q$2.$ The pressure difference between the suction $($inlet$)$ and discharge $($outlet$)$ section of the water pump was measured as $70$ kPa $.$ Assuming the pump's suction and discharge pipes are of the same diameter and with negligible losses, determine the maximum height, $h$ of the water jet.

$h=24\mathrm{.}14m$

$(3$ marks$)$

$($c$)$ If head loss is to be considered in the fountain design of Q$2($b$),$ will the actual water jet rise be higher or lower? Briefly explain your answer.
