Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

**Problem 3:** A rocket with a fixed mass flow rate will continue to increase its velocity (accelerate) while it is expelling mass. A cart, on a frictionless surface with a vertical flat plate being pushed by a horizontal steady jet of water from a fixed nozzle, will accelerate to some fixed velocity. Explain why the rocket's velocity is not fixed, but the cart's velocity is.

**Diagram Explanation:**

The diagram on the left illustrates Problem 3. A red cart is situated on a frictionless horizontal surface. A vertical flat plate is attached to the cart. From the left, a horizontal jet of water is being expelled from a nozzle and hitting the plate, causing the cart to move to the right. This visual helps explain the concept of acceleration in a frictionless environment under the influence of a constant force.

In the jet impact experiment, water jet impacts on a curved vane in the vertical direction. As shown in the figure below, the exit has an angle with respect to the vertical direction. The distance from the nozzle to the vane surface at the exit is h. The water volume flow rate is measured to be Q, the density of water is p, and the cross section area of the nozzle is A₁. Assume that the flow has reached the steady state. (1) Use the Bernoulli's equation to determine the velocity Vout at the exit of the vane. Assume that friction between water and the curved vane can be neglected. (2) Apply the Reynolds transport theorem to derive the expression of the impact force F, on the curved vane (neglect the jet weight). (3) Under the condition of a fixed volume flow rate Q, determine the maximum impact force Fr,max that can be obtained when the angle varies (e.g. in different vane designs). Va out 9 Ao Vout h
