Technicians have to determine the flow rate of water in a pipe with the aid of a venturi installation and a mercury au. oaeter. the expected water welocity is about 1.5 a/s. the pipe diameter is 40 mm and the venturi throat has a diameter of 20 mm. the venturi meter has a discharge coefficient c = 0.97. determine what level difference can be expected in the manometer.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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.
