First midterm 1
(October 8, 2003)
Problem 1: a car collided with a telephone pole and left 20-ft skid marks on the dry
pavement. Based on the damages sustained, an engineer estimated that speed at collision
was 15 miles/hour. If the roadway had a +3% grad

Problem 1:
Two reservoirs are connected by three clean cast iron pipes in series: L1= 300 m, D1= 200
mm; L2= 400 m, D2= 300 mm; L3= 1200 m, D3= 450 mm. If the flow is 360 m/h of water at
20C, determine the difference in elevations of the reservoirs.
