During a static test a certain steel thrust chamber is cooled by water in its coolingjacket. The following data are given for the temperature range and pressure of thecoolant:Average water temperature $100$FThermal conductivity of water $1\mathrm{.}07\backslash$times $104$ Btu$/$sec$-$ft$2-$F$/$ftGas temperature $4500$FSpecific gravity of water $1\mathrm{.}00[$density $=62\mathrm{.}42$ lbm$/$ft$3]$Viscosity of water $2\mathrm{.}5\backslash$times $105$ lbf$-$sec$/$ft$2$Specific heat of water $1\mathrm{.}3$ Btu$/$lb$-$FCooling passage dimensions $1/4\backslash$times $1/2$ in$\mathrm{.}2[$not circular$]$Water flow through passage $0\mathrm{.}585$ lbm$/$secThickness of inner wall $1/8$ in$.$Heat absorbed $1\mathrm{.}3$ Btu$/$in$\mathrm{.}2-$secThermal conductivity of wall material $26$ Btu$/$hr$-$ft$2-$F$/$ftDetermine $($a$)$ the film coefficient of the coolant; $($b$)$ the wall temperature on thecoolant side; $($c$)$ the wall temperature on the gas side.
