How far away from the sluice gate does the jump occur? You can assume the flow is at critical depth on the riser, and that the depth of flow is 1.5 inches from the sluice gate to the beginning of the jump. Where on the channel (in terms of feet from the sluice gate) should have a reinforced bottom? For direct step method use a step size of 0.01 feet.

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

The two required components for a generator are

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
