Note: Assume the liquid surface is open to atmospheric pressure. For Part (b), assume hydrostatics, i.e., ignore frictional losses in the tube. Additional Part: (c) Repeat Part (b) with irreversible head losses included. The following additional information is known: D= 1/8 in., L= 2.2 m, ε= 0 (smooth), µ= 1.52 ×10-3kg/m⋅s, and the volume flow rate is 2.0 L/hr. Ignore all minor losses except the sharp-edged inlet to the tube. For consistency, take the control volume from the surface of the liquid to the location in the tube just upstream of the needle, where Pgage,2= 20 kPa. 2. (10 pts) Text Problem 6.29E. Note: The momentum flux correction factor of the impinging jet is 1.03, and that of the two exiting jets is 1.05. Assume the water is at room temperature (68oF).
