The average wall tube temperature is given to be 35oC. The volumetric flowrate of 2-propanol entering is .00279 m3 /s. Calculate the frictional pressure drop in a straight pipe and the pressure drop in coil. (Use equation 6-37 of Perry’s Handbook (9th edition) to calculate for fanning friction factoAir is allowed to flow from a tank with temperature of 69.8 °F and with pressure of 49.3461 atm through a pipe. It was measured that flow rate is 2.2046 lbm/sec. At some point on the tube static pressure pressure was measured to be 22501.845 mmHg. Assume that process is isentropic and neglects the velocity at the reservoir, calculate the pipe diameter (answer in whole number, unit is mm). Assumed that the ratio of specific heats is 1.4.Given water at 25 deg C flowing in a inclined plate with angle 35 degrees with the horizontal, calculate the velocity and shear stress at the middle of the film and the maximum velocity.
