The two tanks A and B are connected using a manometer. Air is trapped in tank B and in line CD as shown in (Eigure 1). Take p. = 900 kg/m³. P = 1000 kg/m³ Figure 2m O Water 2 125 ml 05a Air 8 1 of 1 Waler 15 m Part A If waste oll is poured into tank A to a depth of h-0.4 m, determine the gage pressure of the entrapped air in tank B.

4. A differential manometer is connected at the two points A and B of two pipes as shown in the figure. The pipe A contains a liquid of S.G. = 1.5 while pipe B contains a liquid of S.G. = 0.9. The pressures at A and B are 98.1 kPa and 176.58 kPa, respectively. Find the difference (h) in mercury level in the differential manometer. Use S.G. = 13.6 for mercury. S.G. = 1.5 IX 13m nnnnnn 2.0 m S.G.= 0.9

9. Determine the height that 20°C water would climb in a vertical 0.02 cm-diameter tube if it attaches to the wall with an angle B of 30° to the vertical.

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.

Q 2/ Calculate the difference between PRESSURE OF COMPRESSED AIR at point A and PRESSURE OF CONFINED WATER at point B located in pipes shown in Figure bellow. (PA- PB). Water B 3 m Water Air 1.5 m Air 1.2 m

Q1: A vertical conduit is carrying oil (S.g 0.95). A differential mercury manometer is tapped into the conduit at points A and B. Determine (a) the difference in pressure between A and B. (b) the difference head between A and B? Take (specific weight for water =62.4 Ibr/ft³, specific weight for mercury = 847 Ibr/ft³). Dil B 18 in 2 in fr = 3 in Mercury
