Answer the following questions: 1. A clean circular glass tube is to be selected in the design of a manometer to measure the pressure of Kerosene . Specific gravity of kerosene = 0.82 and surface tension of kerosene = 0.025 N/m. If the capillary rise is to be limited to 1 mm, the smallest diameter (cm) of the galss tube should be most nearly a) 1.35 b) 1.5 c) 1.75 d) 2.00 2. Both a gage and manometer are connected to a gas tank to measure its pressure. If the reading on the pressure gage is 80 kPa. The distance between the two fluid levels of the manometer h is ..... if the gage fluid in the manometer is a mercury (s 13.6); and h is if the gage fluid in the manometer is water. a) 0.4 m; 9m b) 0.9m; 4.3 m c) 6.213m; 0.7626 m d) 4.91m; 0.668m P= 80 kPa h = ? 3. A 50-ton, 6-m diameter hemispherical dome on a level surface is filled with water as shown in figure. An engineer claims that be can left this dome by attaching a long tube to the top and filling it with water. So, the required height of water h in the tube to lift the dome is the weight of the tube and water therein. Ignore a) 0.47 m b) 7.4 m c) 3.765 m d) 0.935 m
