Water flows through a $2\mathrm{.}5-$cm$-$ID pipe $1\mathrm{.}5$m long at a rate of $1\mathrm{.}0$ kg$/$s$.$The pressure drop is $7$ kPa through the $1\mathrm{.}5-$m length. The pipe walltemperature is maintained at a constant temperature of $50$oC by acondensing vapor, and the inlet water temperature is $20$oC$.$ Estimatethe exit water temperature.Hint: Assume the average temperature $2530$try to usephysical properties of water at the temperature $(25+50)/2(30+50)/2.$
