A tank contains 1 m³ of water at 20°C and has a drawn-capillary outlet tube at the bottom as shown in the figure below. The diameter of the tube is 3.7 cm. 1m 1 m³ L = 80 cm Find the flow rate if the fluid is SAE 10 oil. For SAE 10 oil at 20°C, take p = 870 kg/m3 and μ = 0.104 kg/m-s. For drawn tubing, take & 0.0015 mm.

Air having density p = 0.981 kg/m³ is flowing in a wind tunnel. A differential manometer connected to a pitot tube is used to measure the dynamic pressure of the air at the pitot tube location. The liquid in the manometer is oil having a specific gravity of 0.826, and the manometer reading is 76.2 mm. The wind tunnel is on the CU campus in Denver where g = 9.796 m/s?. a) Find the dynamic pressure of the air (answer: 615.8 Pa). b) Find the speed of the air at the pitot tube location (answer: 35.4 m/s). Air p = 0.981 kg/m³ h = 76.2 mm Oil, SG = 0.826

A joining elbow on horizontal plane is shown in the figure. The fluid is water and assumed to be ideal. Pipe 2 is open to the atmosphere. The flow velocity of pipe 2 is given as Uz = [2+ (k/10)] m/s, and pressure at pipe 3 is p3 = 1.6 + k/ 4 kPa. (k=5) a) Calculate the flow velocity at pipe 3 (u3 = ?) b) Calculate the discharge and flow velocity of pipe 1 (Q = ?, ui = ?). c) Calculate the pressure at pipe 1 (p. = ?). d) Calculate the x and y components of the net force acting on the joining elbow by the fluid.
