1. (a) Define: - Fluid viscosity, capillarity, Cavitation, Water Hammer and Specific weight. (b) Draw the neat sketch of Rheological Diagram, What are the causes of viscosity? (c) Find the dimension of the kinematic Viscosity. A rectangular plate of 1.2m long and 0.25 m thick weighing 1.2KN slides down an inclined plane making an angle 35 with horizontal at a velocity of 2.5 m/s. If the 1.8mm gap between plate and inclined surface which is filled by lubricating oil, find the viscosity of oil in terms of poise. (d) State and deduce the Pascal's law. Find the force required to lift a weight of 25KN by means of hydraulic jack which a ram of 150mm and plunger of 25mm diameter respectively. If the plunger has a stroke of 0.5m and if it makes 30 strokes/min, find the required at the plunger. 5*4= 20 1.
