0 0 votes In a counter-flow heat exchanger, water is heated at the rate of $1.5 \: kg/s$ from $40^{\circ}$ C to $80^{\circ} \: C$ by an oil entering at $120^{\circ}$ C and leaving at $60 ^{\circ}$ C. The specific heats of water and oil are $4.2 \: kJ/kg.K$ and $2 \: kJ/kg.K$, respectively. The overall heat transfer coefficient is $400 W/m^{2}.K$. The required heat transfer surface area (in $m^{2}$) is $0.104$ $0.022$ $10.4$ $21.84$ Heat Transfer gateme-2017-set2 fluid-mechanics-and-thermal-science heat-transfer heat-exchanger + – ♦Arjun 346 views answer comment Share Follow Add Sync Questions 0 reply Please log in or register to add a comment.
