Arectangular channel has a gradual contraction in width from 59ft to 30ft and a bed level drop of 6in. below the upstream channel bed, which the increased velocity caused by the contraction scoured. if the upstream and downstream flow depths are both 10.1ft, compute the discharge in the channel.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

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.
