Engine oil at 94 "C flows over the upper surface of a 5-m long, 2-m wide flat plae whone surface temperature is 20 "C with a velocity of 2 m/s Oil properties at film temperature, 57 °C: p-8658 kg/m' ; μ-8, 39 x 10" Pas; s. 0.141 W/m.K; Pr 1205 flow over the entire plate laminar or turbulent? (b) Determine the heat transfer coeficient, h, of oil flow over the surface (c) Determine the rate of heat transfer to the...
Oil (density 900 kg/m' and absolute viscosity 0.2 kg/m-s) flows through a pipe 20-m-long and 4-cm wide in inner diameter a- The flow rate is 47 liters/min. when the pipe is laid horizontally. Calculate the pressure needed at the pipe inlet. (7 points) b- If the exit end of pipe is raised by 0.2 m, please find the flow rate at this slope while the inlet pressure remains the same as in the situation (a). (8 points) (a) Air 0.2m...
