Q8/ Water at 20 °C flows over a flat plate at 80°C. If the heat transfer coefficient is 200W/m².°C. Determine the heat flow per square meter of the plate (heat flux). Answer: 12kW/m² Q9/ Air at 200°C flows over a flat plate maintained at 50°C. If the heat 20 transfer coefficient for forced convection is 300W/m. C. Determine the heat transferred to the plate through 5m over a period of 2h. Answer: 450kW.h Q10/ Water at 50°C flows through a 5-cm diameter, 2-m-long with an inside surface temperature maintained at 150°C. If the heat transfer coefficient between the water and inside surface of the tube is 1000W/m².°C, determine the heat transfer rate between the tube and the water. Answer: 31.4kW
