Carbon dioxide flows in a horizontal 100 mm wrought iron pipeline at a velocity of 3 m/s. At a point in the line a pressure gage reads 690 kPa and the temperature is 40°C. What pressure is lost as the result of friction in 30 m of this pipe? Barometric pressure is 101.3 kPa. Assume the fluid is of constant density

Water flows steadily through a horizontal 30 degree pipe bend. At the inlet point 1, the diameter is 0.3 m, the velocity is 12 m/s, and the pressure is 128 kPa gauge. At the outlet point 2, the diameter is 0.38 m and the pressure is 145 kPa gauge. Determine the forces F_x and F_y necessary to hold the pipe stationary.

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

Find the horizontal and vertical forces to hold stationary the nozzle shown in the figure below. The fluid flowing through it is 10 °C liquid water; A₁ = 1.2 m², A₂ = 0.300 m², V₁ = 15 m/s, p2 = Patm and p₁ = Patm + 75 kPa. Neglect effects of gravity.
