A 0.6-mm-diameter glass tube is inserted into water at 20°C in a cup. The surface tension of water at 20°C is ?s = 0.073 N/m. The contact angle can be taken as zero degrees. The capillary rise of water in the tube is (a) 2.6 cm (b) 7.1 cm (c) 5.0 cm (d ) 9.7 cm (e) 12.0 cm

A 1m x 2m inclined plate is submerged as shown. The normal force acting on the upper surface of the plate due to the water (when taking atmospheric pressure into account) is most nearly (A) 68kN (B) 91kN (C) 203kN (D) 294kN Answer is 294kN please include explanation as it's important question.

A 80 cm tall cylinder is filled with water (ρwater = 1000 kg/m3) and oil (ρoil = 600 kg/m3) and is capped on the bottom so no fluid is flowing. It contains equal amounts of the two fluids by weight. What is the pressure at the bottom of the cup?

A circular tank at a storage facility is 10 metres diameter andcontains transformer oil of mass density 885 kg/m3 to a depth of 6.5metres.(i) Draw the pressure distribution diagram for the side of thetank noting all significant values and showing the position ofthe force due to oil on the side of the tank relative to the oilsurface. (ii) Calculate the ground pressure under the full tank (in kPa)neglecting the weight of the tank.
