1) Assuming that water at 20 C is flowing through the system at a constant flow rate of 2
ft³/sec and neglecting viscous effects, calculate the EL and HGL at points A, B, and C. Sketch
the EL and HGL alongside the diagram.
A
ZA = 55 ft
D₁ = 3 in
B
D₂ = 6 in
C
2) What is the elevation at point C in the above figure?
3) Using the figure from problem 1, sketch the EL and HGL accounting for both major and
minor losses. Note that the flow rate will change due to the introduction of friction (we will
explore this further in the coming weeks). You do not need to calculate the values of EL and
HGL.
8) Carbon dioxide at 20 C is transported through a pipe of 0.1 m in diameter. What is the
maximum flow rate possible to achieve laminar flow?
7) In the below diagram, the pipe diameter is 10 cm and the flow rate in the pipe is 0.3
m³/sec. At this flow rate, the pump will generate 90 m of head. The pressure at point A
is 500 Pa and the water in the pipe is at 60 C.
a) Taking the datum to be at the centerline of the pump, calculate the EL and HGL at
points A and B, neglecting friction.
b) What is the pressure at point B?

The pair has to choose a suitable sustained service live load (from 300-1500plf) and superimposed dead load (50-150plf) and has no concrete topping. Assume the beam is made of normal-weight concrete with fc'= 5,000 psi and that the concrete strength f'ci at transfer is 70 percent of the cylinder strength. . Also, the pair must assume a justifiable time-dependent loss. • Assume that that fu = 260,000 psi for stress-relieved tendons, ft = 12sqrt(fc').
