You are about to ride a roller-coaster at Disney. The ride is a single-person ride with a drop of 25.0 meters and a plunger/piston system that makes the ride stop. There is a 250 kg water cylinder attached to the plunger/piston. The cart weighs about 75.0 kg and begins at the top of the circuit at a standstill. To get the total mass of the cart during the ride, you must add your weight (55KG) to the cart's overall weight. According to analysis, friction in the wheels and axles creates 2750 J of combined thermal and sound energy when the cart moves along the track. The bottom of the device's plunger/piston is designed to stop the cart at a max acceleration of 5.00 g's (49.0 m/s2). Question: Question #5: The plunger/piston compresses the water inside the cylinder, which is thenturned into thermal energy within the water. Determine the temperature change of the waterin the cylinder as it pulls the cart to a stop if the specific heat capacity of water is 4184J/kg°C (assuming 100 percent…

A cylindrical tank with a radius of 3ft is filled with water which has a weight density of 62.4 lb/ft^3. The water is to be pumped to a point 2ft above the top of the tank. (a) How much work is performed in pumping all the water from the tank? (B) How much work is performed in pumping 3ft of water from the tank? (C) At what point is 1/2 of the total work done?
(Just Question a.) A water filled pipe has water flowing at v1= 5.90 m/s in a section of pipe where the diameter is d1= 20.2 cm and the pressure is known to be P1= 7.00×104 N/m2 above atmospheric pressure. If the pipe carries the water 3.5 meters up hill without any change in diameter, what is the new absolute pressure within the pipe? After flowing up the hill described above, the pipe narrows to 80% of its original radius, what will be the new water velocity (v2) in the pipe? What will be the absolute pressure (P3) in the smaller pipe? a. What is the volume flow rate through the smaller pipe?
A stationary water tank of diameter D is mounted on wheels and is placed on a nearly frictionless level surface. A smooth hole of diameter Do near the bottom of the tank allows water to jet horizontally and rearward and the water jet force propels the system forward. The water in the tank is much heavier than the tank-and-wheel assembly, so only the mass of water remaining in the tank needs to be considered in this problem. Considering the decrease in the mass of water with time, develop relations for (a) the acceleration, (b) the velocity, and (c) the distance traveled by the system as a function of time.
The Super Soaker XP30 is a marvel of hydraulic dispersion weaponry. By pumping on the handle, you charge the chamber to high pressure. The pressure is maintained until you pull the trigger at which point the water (? = 1000 kg/m3) is released at high velocity.You have charged your pressure chamber to an absolute pressure of P1 = 697500 Pascals, much higher than today's outside air pressure of 101300 Pascals. The pressure chamber is location at a height of y1 = 0.103 meters above the exit point. The exit point has a small opening with radius r = 0.0033 meters.Determine all the following:The velocity at which the water exits the Super Soaker: v2 = m/sThe mass flow rate through the exit: kg/secThe volume flow rate through the exit: m3/secNOTE: You may treat the water chamber as a "tank" and approximate the water velocity there to be zero.
