A piston 11.96 cm diameter and 14 cm long works in a cylinder 12 cm diameter. A lubricating oil which fills the space between them has viscosity 0.65 poise. Calculate the speed at which the piston will move through the cylinder when an axial load of 0.86 kg is applied. Neglect the inertia of the piston. 14 cm VF- 0.86 Kg,t

Jet. of liquid (14 mm diameter) ejections vertically into the atmosphere. The pressure inside the jet (due to surface tension) will be slightly higher than the atmospheric pressure. Determine the difference in pressure (in Pascal). (take o 8.35*10-2 N/m for liquid)

Question - Civil hydraulics The diameter of the U-tube is one-tenth the diameter of the enlarged ends, and a double column enlarged ends manometer is used to measure a minor pressure differential between two points of a system transporting air under pressure. Water is employed as the heavy liquid, and oil with a relative density of 0-82 is used as the lighter liquid in both limbs. Calculate the difference in pressure in millimetres of water for a manometer displacement of 50 mm, presuming the lighter liquid's surfaces stay in the larger ends. If carbon tetrachloride, which has a relative density of 1.6, were used in place of water but the pressure conditions remained the same, what would the manometer read?

A flocculate is designed to achieve a velocity gradient of 50 s with a volume of 3000 m' .the viscosity of the water is 1.1x10 Pa-sec. The coefficient of drag paddle is 1.8 and paddle tip velocity is 0.8 m/sec. The relative velocity of the paddle is with respect to water is 70% of paddle tip velocity. The mass density of water is 1002 kg/m. Calculate the power required for paddles and total area of the paddle blades. a) 7.57 kW and 45.98 m² b) 9.12 kW and 60.53 m² c) 8.25 kW and 52.10 m² d) 6.38 kW and 39.59 m?
