Question $1$: $[15$ marks$]$

Water flows through a ${2\mathrm{.}375}^{\text{'}\text{'}}$ diameter pipe. The pipe is heated on the outside by steam at $230F.$ The overall heat transfer coefficient is $250Bt\frac{u}{h}rf{t}^{2}F$ based on the outside area of the pipe. If the inlet and outlet temperatures for a $1$ ft length of pipe are $80F$ and $180F,$ what is the water flow rate in $l\frac{b}{h}r?$ Given: $1k\frac{J}{s}=3412Bt\frac{u}{h},2\mathrm{.}205lb=1$kgQuestion $1$: $[15$ marks$]$
