1-71. Water in the glass tube is at a temperature of 40°C. Plot the height h of the water as a function of the tube's inner diameter D for 0.5 mm s Ds 3 mm. Use increments of 0.5 mm. Take a = 69.6 mN/m. Prob. 1-71

Calculate the pressure at point A in the manoter shown. beight b'c = 0.50m

Ex. A pitot static probe is inserted into duct of air heating system parall to flow and the differential height of the water Colum is measured. The flow velocity and the pressure rise at the of the pitot -statics probe are to be determined For water p = 1000 kg/m3. for air p = 1.1 kg/m3 Air h-2.4 cm

1 valve Ah 2 Part B If R = 3.21 in and P2 = Patm = 12.2 psi, find P₁ in [psi]. X Part A A manometer is used to measure the pressure drop across a valve as shown above. Use the equation P = yh to show that AP = P₂ - P₁ = Ah(yw - Ym), where Ah is the manometer reading, Yw is the specific weight of water, and Ym is the specific weight of mercury.
