Arectangular river channel, 7 m wide, carries water at a depth of 1.4 m. the slope of the channel is 1/500. the channel has poor alignment and the bed is covered with stones such that a manning's n value of 0.06 is appropriate. calculate the flow rate in the channel and prove whether the flow is sub-critical or super- critical. [5 marks] (c) for a rectangular channel, determine the relationship between its width, w, and depth, d, that will result in the maximum discharge.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
