Homework #4
Due Feb 22, 2008
Spring Semester 2008
1] Output from a fire hose is directed at a wall. The flow rate through the hose is 100
gallons/minute. Assume an all-water jet of 1/2” diameter emerges from the hose and is
directed at a vertical wall (like the side of a building). Estimate the force on the building in
[lbf].
2] A very large group of pitchers stands near a wall and throws baseballs (5 oz each) at the wall
at 100 mph each. On average, 44 baseballs hit the wall every second. Estimate the average
force on the wall in [lbf].
3] Water flows through a 50 cm wide by 1 m deep (into the page) duct. Gate BC completely
closes the duct when β = 90°. Assuming one dimensional flow, for what angle β will the force
of the exit jet on the plate be 3 kN?
4] The water tank stands on a frictionless cart and feeds a jet of diameter 4 cm and velocity 8
m/s, which is deflected 60° by a vane. Compute the tension in the supporting cable.
