Show that the kinetic energy of oil flowing through a pipe is 1.2961 ft-lbf/s given the folowwing: diameter of pipe = 2 in Flow rate = 40 gal/min SG = 0.90 water density = 62.3 lb/ft3

If the difference between the total pressure and static pressure in an air duct is measured by a pitot tube to be 6.5 cm H2O, what is the flow velocity in m/s? Density of water is 998 kg/m3, and g = 9.81 m/s2. 3 signififcant figures answer

Water flows from Reservoir A to Reservoir B. The pipe diameter D is 1 m, and the pipe length L is 300 m. H= 16 m, h = 2 m, and the pipe head loss is given by h₁ = 0.01), where U is the velocity in the pipe. In your solutions consider the head loss at the pipe outlet to be ( U² 2g (a) what is the discharge in the pipe? (b) What is the pressure at point P halfway between the two reservoirs? (c) sketch the HGL and EGL. Water D H P B

= = Air flows radially outward between the two parallel circular plates shown in the figure below. The pressure at the outer radius, Ro 5 cm, is atmospheric. Find the pressure at the inner radius R¿ 0.5 cm, if the air density is constant, the air flow is inviscid, the volume flow rate is 4.0 L/s, and the plate spacing is h = 0.125 cm. h Po= Patm = 101.3 kPa T = 20°C 777 R₁ Ra
