A fuel oil heater is designed to counterflow heat transfer is used to heat fuel oil from 25 °C to 99 °C while the heating fluid enters at 150 °C and leaves at 105 °C. The fuel oil has a specific gravity of 25 °API (you may check formula from internet or books for computing SG using this API if you have not yet encounter in your previous subjects, use this SG to find density at another temperature), a specific heat of 0.65 kcal/kg- °C and enters the heater at the rate of 2600 liters per hour. Determine LMTD and heating surface area if U=130 kcal/hr-m2- °C.
