MODEL ANSWER PAPER
Q.1 Explain Newton law of viscosity
ANS:
Q. 2 A Plate 0.025 mm distant from a fixed plate, moves at 60 cm/s and require a force of 2N per
unit area i.e 2N/m2 to maintain the speed Determine the fluid viscosity between the plates.
Q.2 A differential manometer is connected a two point A and B of two pipes as shown in fig. The pipe A contain a liquid of sp.gr.= 1.5 While pipe B contains a liquid Sp.gr = 0.9. The pressure A and B are 1 Kgf/cm2 and 1.80 Kgs/cm2 respectively. Find the difference in mercury level in differential manometer (5)
Q.3 Derive an expression for the depth of centre of pressure from free surface of liquid of an inclined plane surface sub-merged in the liquid (5)
Q.4 a rectangular plane surface 2 m wide and 3 m deep lies in water in such a way that its plane makes an angle of 300 with the free surface of water. Determine the total pressure and position of centre of pressure when the upper edge is 1.5m below the free water surface (5)
(5)Derive the continuity equation in three dimensional (5)
