For instructor or TA use only: Problem Score Points 1 15 2 10 3 15 4 30 5 10 6 10 7 10 ME 33 Fall Semester, 2005 Homework Set # 9 Professor J. M. Cimbala Total: 100 1 . (15 pts) Text Problem 3.123 . 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 -3 kg/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 P gage,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 (68 o F).
