31.A fluid which has a linear relationship between the magnitude of applied shear-stress and the resulting rate of deformation is called a/an _________ fluid.
32.A fluid whose apparent viscosity increases with shear rate is termed as the _________ fluid.
33.A gas (density = 1.5 kg/m3, viscosity = 2 × 10‒5 kg/m.s) flowing through a packed bed (particle size = 0.5 cm, porosity = 0.5) at a superficial velocity of 2 m/s causes a pressure drop of 8400 Pa/m. The pressure drop for another gas, with density of 1.5 kg/m3and viscosity of 3 × 10‒5kg/m.s flowing at 3 m/s will be

36.A hydraulic press has a ram of 10 cms in diameter and a plunger of 1 cm in diameter. The force required on the plunger to raise a weight of 10 tons on the ram is _________ kg.
37.A hydraulic ram acts as a/an _________ pump.
38.A liquid is pumped at the rate of 600 litres using 1000 rpm. If the rpm is changed to 1100, the liquid pumped is _________ litres.
39.A lubricant 100 times more viscous than water would have a viscosity (in Pa.s)
40.A mercury (specific gravity = 13.6) manometer connected across an orificemeter fitted in a pipe shows a manometer reading of 2 cms. If the manometer liquid is changed to carbon tetrachloride (specific gravity = 1.6), then for the same flow rate of water the new manometer reading will be _________ cms.
