- Example 2.8. The inlet to pump is 10.5 m above the bottom of sump from which it draws water through a suction pipe. If the pressure at the pump inlet is not to fall below 28 kN/m absolute, work out the minimum depth of water in the tank. Assume atmospheric pressure as 100 kPa.arrow_forwardPlease provide solutions. 1. A pipe 2.50 cm in diameter is 1.0 m long and filled with 0.60 m of water. If the pipe is capped at both ends and rotated in a horizontal plane about a vertical axis through one end of the pipe, what is the pressure at the other end of the pipe when it is rotating at 200 RPM? Problem A: An open vertical cylindrical tank 0.60 m in diameter and 1.20 m high is half full of water. If it is rotated about its vertical axis so that the water just reach the top, find the speed of rotation. What will then be the maximum pressure in the tank? If the water were 1.0 m deep, what speed will cause the water to just reach the top? What is the depth of the water at the center? 2. If the tank of Prob. A is half full of oil (sp. gr. 0.75) what speed of rotation is necessary to expose one-half of the bottom diameter? How much oil is lost in attaining this speed? Answer: 18.70 rad/s ; 42.5 litresarrow_forward4. The right limb of a simple U-tube manometer containing mercury is open to the atmosphere while the left limb is connected to a pipe in which a fluid of sp.gravity 0.9 is flowing. The centre of the pipe is 12 cm below the level of mercury in the right limb. Find the pressure of fluid in the pipe if the difference of mercury level in the two limb is 20 cm . And also draw the arrangements.arrow_forward
- Q2 (a) An apparatus shown in Figure Q2 consists of a rubber squeeze bulb filled with sand connected to a glass tube. The bulb and sand are completely saturated with water. If the bulb is squeezed. (i) By assuming that the sand is dense sand, examine what happens to the water level in the glass tube and give reason to the answer (ii) By assuming that the sand is loose sand, examine what happens to the water level in the glass tube and give reason to the answerarrow_forwardProblem 1. A 6m diameter cylinder rests on the bottom of the tank (lowest point is A) which is 4m perpendicular to the paper. Óil (0.80) and liquid Z(0.98) are poured into the left and right portions of the tank to depths of 3.5m and 5m respectively. Find the magnitudes of the: a. Horizontal component of the force acting on the cylinder b. Vertical component of the force acting on the cylinder that will push up the cylinder. c. and determine the specific weight of the material composition of the cylinder required to keep it touching point Aarrow_forward7. A horizontal cylindrical triangle boiler, length 2.5 m and radius of base 0.6 m, is being filled with water at the rate of 0.09 min .How fast is the water rising in the boiler when the water is 0.3 m deep?arrow_forward
- The two sides of a V-shaped water trough are hinged to each other at the bottom where they meet, as shown in Fig. 5, making an angle of 45° with the ground from both sides. Each side is 0.75 m wide, and the two parts are held together by a cable and turnbuckle placed every 6 m along the length of the trough. Calculate the tension in each cable when the trough is filled to the rimarrow_forwardThe tube shown in Fig. 32 is filled with oil. Determine the pressure heads at A and B in meters of water.

Take density of the oil as 1 kg/litre. Neglect weight of the drum.arrow_forward
- PROBLEM 4 An open cylindrical tank 4 ft In diameter and 6 ft deep is filled with water up to its rim and rotated about its axis at 60 rpm. (a) What is the height, h, of the parabolold formed? Express the answer In ft. (b) How much water remained in the tank? Express the answer In ft². (c) How much water is spilled? Express the answer in ft². (d) What is the maximum pressure (psf) at the bottom of the tank? (e) What is the minimum pressure (psf) at the bottom of the tank?arrow_forwardExample 3.5. A square aperture in the vertical side of a tank has one diagonal vertical and is completely covered by a plane plate hinged along one of the upper sides of the aperture. The diagonals of the aperture are 2.4 m long and the tank contains a liquid of specific gravity 1.2. The centre of aperture is 1.8 m below the free surface. Calculate: (i) The thrust exerted on the plate by the liquid; (ii) The position of its centre of pressure. (Anna University)arrow_forwardA container lying horizontally is filled with water. It is 5 ft long and its cross section is in the shape of a semicircle with diameter 3 ft at the top. The weight density of water is 62. 4 lb/ft. (Draw an illustration.) a. How much work is required to pump all the water to the top of the tank? b. Find the force due to fluid pressure on one semicircular end of the container.arrow_forward
