QUESTION $235$ points

A solar flat$-$plate collector $($FPC$)$ supplies hot water for radiant floor heating system at $320$ K with a capacityof $10$ kW $.$ Solar $I_n$ is $700\frac{W}{m^2}.$ The first law efficiency, ${}_{\text{I}}$ is $0\mathrm{.}6.T_{\text{r}\text{e}\text{f}}=283K$ a$-10$ point. What is the input exergy, Exsolur?

$b-10$ point. What is the unit output exergy, $E_{\text{X}\text{o}\text{u}\text{t}\text{p}\text{u}\text{t}}$ at $320K?\frac{I_n}{1367}=\frac{{}_{\text{s}\text{o}\text{l}\text{a}\text{r}}}{0\mathrm{.}95}=\frac{(1-\frac{T_{\text{r}\text{e}\text{f}}}{T_f^{**}})}{0\mathrm{.}95}$ c$-10$ point. What is the exergy destruction?

d$-5$ point. What is the Exergy Efficiency?

$E_{\text{x}\text{o}\text{u}\text{t}\text{p}\text{u}\text{t}}=Q{}_{\text{I}}(1-$ Tre$\frac{f}{320}K)$
