open deep specific gravity 0.85 to a depth of 1.4 m. If the tank is accelerated along its length on a horizontal track at a constant acceleration 4.5 m/s2, determine: 1) The new position of the oil surface. 2) Pressures at the bottom of the tank at the front and rear edges.

A door in the side of a tank is 20cm wide and 30cm high. If the tank is filled with oil r.d. 0.82 to the top of the door what is the force exerted on the door and the position of its line of action How much oil will have to be drained out for the force to be 40N and what will be the position of the new line of action

3. An 8 ft diameter cylinder weights 500 lb and rests on the bottom of a tank that is 3 ft long. Water and oil (SG=0.75) are poured into the left and right hand portions of the tank to the depths of 2 ft and 4 ft respectively. Assume that water has a specific weight of 62.4 lb/ft³. a) Compute the magnitude of the horizontal forces pushing on the tank. What is the net force? 2 2 3.4642 D B sp gr 0.750 b) Compute the magnitude of the net vertical forces pushing on each side of the tank.

Water flows in a channel with uniform curvature R. The channel has height h = 6 mm and width w=190 mm (normal to the drawing plane) as shown in Fig Q3. The curved part of the channel has a length of 1 =95 mm in the x-direction. You can assume that the channel height is very small compared to the curvature radius. Neglect effects of gravity. channel y V X 1 lower wall h upper wall centreline Fig Q3: Geometry of curved channel, drawing not to scale. The curvature of the channel is not shown, as too small to be drawn accurately at this scale. Work to 4 significant digits. Enter all values using base units or their combinations, i.e. m, m/s, Pa, N. Do not use multiples as e.g. mm, kPa. You can use values with exponents, such as 0.12e3.
