Saturated vapour is condensed to saturated liquid in a condenser. The heat capacity ratio is Cr = $\frac{^Cmin}{^Cmax}$. The effectiveness (e) of the condenser is

  1. $\frac{1-exp[-NTU(1+C_r)]}{1+C_r}$
  2. $\frac{1-exp[-NTU(1-C_r)]}{1-C_rexp[-NTU(1-C_r)]}$
  3. $\frac{NTU}{1+NTU}$
  4. $1-exp(-NTU)$
