Problem $08\mathrm{.}045-$ Rate of heat transfer and entropy generation in heat exchanger.

Cold water leading to a shower enters a well$-$insulated, thin$-$walled, double$-$plpe, counterflow heat exchanger at $10C$ at a rate of $0\mathrm{.}800k\frac{g}{s}$ and is heated to $70C$ by hot water that enters at $85C$ at a rate of $1\mathrm{.}6k\frac{g}{s}.$ Use data from the tables.

Problem $08\mathrm{.}045.$a $-$ Heat transfer to cold water in a heat exchanger

Determine the rate of heat transfer.

The rate of heat transfer to the cold water is $$ kW$.$

Cold water leading to a shower enters a well$-$insulated, thin$-$walled, double$-$pipe, counterflow heat exchanger at $10C$ at a rate of $0\mathrm{.}800k\frac{g}{s}$ and is heated to $70C$ by hot water that enters at $85C$ at a rate of $1\mathrm{.}6k\frac{g}{s}.$ Use data from the tables.

Problem $08\mathrm{.}045.$b $-$ Rate of entropy generation in the heat exchanger

Determine the rate of entropy generation in the heat exchanger. $($Round the final answer to five decimal places.$)$

The rate of entropy generation in the heat exchanger is $$ kW$/$K$.$
