Compute points on the velocity profile from the tube wall to the centerline of a
standard hydraulic steel tube, 50 mm OD x 1.5 mm wall, if the volume flow rate
of SAE 30 oil (sg = 0.89) at 110°C is 25 L/min. Use increments of 4.0 mm and
include the velocity at the centerline.|
A Forced - Draft (FDF) with open suction has rated capacity of 4,000 CFM at 1,800 rpm. The pressure developed at the discharged duct is 10 mm H2O. The discharge duct is circular with inside diameter of 600 mm. Calculate the following:a) what is the velocity of air at the discharge in mm H2O?b) what is the theoretical fan power required in kW?Consider standard density of water and air are 1000 kg/m3 and 1.20 kg/m
