20 liters of an incompressible liquid exert a force of 50 n on the surface of the moon (g = 1.67 m/s2). what force will 7.6 liters of the liquid exert on the surface of the earth?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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.
