Problem $1$:

A sugar solution and $=1\mathrm{.}3{10}^{-3}N.\frac{s}{m^2})$ flows at a rate of $60000k\frac{g}{h}r$ and is to be heated from $25C$ to $40C.$ Water at $95C$ is available at a flow rate of $75000k\frac{g}{h}r.$ It is proposed to use a $12-in.-$ID$,1-2$ shell and tube heat exchanger containing $3/4-$in$.-$OD$,16$ BWG tubes, $1m$ long and laid out on a $1-$in$.$ square pitch. The exchanger contains three baffles spaced evenly. Will the exchanger be suitable?
