Water flows through a constricted pipe at a uniform rate. At one point, the diameter of the pipe is 43mm and the pressure is 8.3 x 10 4N/m2. At another point, 1 m higher than the previous point, the diameter is 17 mm and the pressure is 2.7 x 104 N/m2 . Calculate the velocities at the lower section and the upper section. Also calculate the rate of flow. Density of water

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.
