Water at 20°C is flowing in a pipe of length 10 m and diameter 10 mm. Inlet pressure is 500 kPa and outlet is at 1 arm. Determine the flow rate in liters per second if the pipe is (a) horizontal, (6) inclined at 20° with flow upward, (c) inclined at 20° with downward flow.

In an experimental setup for a pipe flow, velocity is measured at two different points. Point 1 is 1 cm away and point 2 is 2 cm away from the pipe wall. If the increase in the velocity from point 1 co point 2 is 16%, estimate the roughness t: for the pipe surface.
