1.A channel 5m wide at the top and 2m deep has sides sloping 2 vertically in 1 horizontally. The slope of the channel is 1 in 1000. Find the volume rate of flow when the depth of water is constant at 1m. Take c = 53 in si units. What will be the depth of water if the flow were to be doubled?
1.A channel 5m wide at the top and 2m deep has sides sloping 2 vertically in 1 horizontally.
The slope of the channel is 1 in 1000. Find the volume rate of flow when the depth of water
is constant at 1m. Take c = 53 in si units. What will be the depth of water if the flow were to
be doubled?
2.A 2.0m diameter concrete pipe on a slope of 0.005 is to carry water at a normal depth of
1.5m. Determine the flow velocity and flow rate. Take n=0.014. Also determine q when
ho=0.75 and h=1.0m
3.A trapezoidal channel is to be designed to carry 280m3/minute of water. Determine the
cross – sectional dimensions of the channel if the slope is 1 in 1600, side slopes 45o
and the
cross – section is to be a minimum, take c = 50 in si units.
