A rectangular channel 5 m wide carries a discharge of 15+Y m3/s. The observed velocity at a particular point in the channel is 2.0 m/s. (Y= 3).  a. What is the specific energy of the flow at this point? b. What is the critical depth and critical velocity in the channel? c. hat will be the step up necessary that will produce critical depth? d. If you have to create critical depth by narrowing the width of the channel what will be width? e. If you decide to create critical depth using slope, calculate the slope with n=0.03.

1- Uniform flow passes through a rectangular channel having a width of 4 m. The channel carriers a discharge of 12 m³/s with a depth of 3 m at section 1. The bed is raised in section 2 by 20 cm and the velocity distribution changes due to bed roughness. Note: The energy loss is 10% of the velocity head at section 2. Velocity profile in section 2 can be expressed by a linear equation as v ky2. a) Write the energy equation b) Calculate the flow depth at section 2 c) Calculate the Froude number at sections 1 and 2 of Side vehw Y/₂ Az
