Redo Example $4\mathrm{.}4\mathrm{.}2$ with P$1=25$ psi and theta$=30$o$.$

EXAMPLE $4\mathrm{.}4\mathrm{.}2$

Water flows through a horizontal$45$ reducing bend shownin Figure$4\mathrm{.}4\mathrm{.}3,$witha$36-$indiameterupstream and a $24-$in diameter downstream, at the rate of $20$ cfs under a pressure of $15$ psi at the upstream end of the bend. Neglecting the headloss in the bend, calculate the force exerted by the water on the bend.Figure $4\mathrm{.}4\mathrm{.}3$ Reducing bend for example $4\mathrm{.}4\mathrm{.}2.$
