Question
(a) A counter flow double-pipe heat exchanger is used to heat from $20^{\circ}\text{C}$ to $40^{\circ}\text{C}$ by cooling oil from $90^{\circ}\text{C}$ to $55^{\circ}\text{C}$. The heat exchanger is designed for a total heat transfer of $59 \text{ KW}$ with an overall heat transfer coefficient of $340 \text{ W/m}^2\text{ }^{\circ}\text{C}$. Calculate surface area of heat exchanger? [12]
(b) Explain about fouling factors? [8]
