Hot water at $95^{\circ} \mathrm{C}$ is used in a plate heat exchanger for heating $2 \mathrm{~kg} \mathrm{~s}^{-1}$ fruit juice from $45^{\circ} \mathrm{C}$ to $75^{\circ} \mathrm{C}$. Specific heat capacity of fruit juice is $3.7 \mathrm{~kJ} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$. Final temperature of the hot water is $70^{\circ} \mathrm{C}$. Overall heat transfer coefficient is $1122 \mathrm{~W} \mathrm{~m}^{-2} \mathrm{~K}^{-1}$. Heat transfer area is $12.75 \mathrm{~m}^{2} .$ The logmean temperature correction factor is____________
