A NASCAR racing team is conducting experiments to determine the suitability of a new fuel, code-named fuel-X. The specific gravity of fuel-X is 0.85. It is accelerated through an ideal conical nozzle which discharges to the atmosphere and impacts a restrictor plate. The inlet diameter of the nozzle is 5 cm and the outlet diameter is 2 cm. Careful measurements by the race team indicate that a reaction of 500 N is required to hold the plate stationary. What is the mass flow rate of the fuel

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

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.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
