A vertical pipe of 40mm diameter carrying a flow of a Crude oil of μ = 1.7 poise and relative density 0.82. The pressure gauges fixed in point A and point B which is above A, the distance between A and B is 50 m. Pressure gage of point A reads 650 kN/m2 and Pressure gage of point B reads 300 kN/m2. Find the direction and rate of flow through the pip

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Compute the pressure drop of 30°c air flowing with a mean velocity of 8 m/s in a circular sheet-metal duct 300 mm in diameter and 15 m long. use a friction factor, f 0.02, and pair = 1.1644 kg/m a. 37.26 pa b. 25.27 pa n c. 29.34 pa d. 30.52 pa
