I want to design vertical sluice gate on river. The river width is 7.3M and depth is 1.5m. So how big the opening of the sluice gate? What is the height after the sluice gate? What is the night after the hydraulic jump? What is the critical depth? Explain about subcritical and supercritical in this situation? Froude number? Anything I have to consider before I design?

Consider the following statements and mark the statement as you answer which is correct in the context of kinetic energy and potential energy.

1. The kinetic energy of a molecule depends on the temperature while potential energy depends upon the position

2. The kinetic energy of an object is due to its position while potential energy is due to its velocity

3.  Both kinetic and potential energy of an object can be maximum at the same time

4. None of these
