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.

Q.2) Explain Reynold’s number based on viscous and inertia forces
Show the complete solution
In a nutshell, a smaller rock is propelled into the air as a huge counterweight in the back falls down, effectively converting gravitational potential energy into kinetic energy for the rock and the weight. But, since the rock is smaller.. it is propelled at a much faster velocity! Let's say we wanted to hurl a 50 kg boulder at a castle wall 100 meters away. Our wooden structure for the trebuchet is 10 meters tall, so that is the maximum distance the counterweight can fall. Assuming the launch angle is a perfect 45 degrees, and the boulder is released from ground level, derive the needed mass of the counterweight that will give the boulder enough kinetic energy to reach the base of the castle walls. You may assume no energy is "lost" due to friction, and ALL the counterweight's gravitational potential energy is converted into the boulder's kinetic enerqy. (HINT: You will need to employ 2D kinematics to find the needed final velocity, then use that final velocity in an energy equation…
Question 2. A fluid of density p is contained in a cylinder of radius R as shown in the Figure below. The cylinder and the fluid are both spinning at an angular velocity w. Due to the spin, the difference in elevation of the fluid's free surface between the rim of the cylinder and its centre is h. Taking the acceleration due to gravity as g, answer the following, while showing all your work: (a) If h is thought to be a function of the other parameters in the problem (R, p, g, and w), generate all the non-dimensional parameters in the problem without choosing the acceleration due to gravity as a repeating variable. (b) Show that at least one of the non-dimensional parameters can be recast as the Froude number for the problem. Additionally, show the functional relationship between the independent and dependent non-dimensional parameters. (c) Through an experimental design of your choice, explain how and with how many experiments, you would determine the functional form of the…
