- A mass-less spring having a spring constant k = 185 N/m, is inside a horizontal barrel. Its left end is rigidly fixed at position x = 0.0 cm, and its right end is at X L, where L = 19.7 cm. The spring is then squeezed so that the right end of the spring is at X = S, where S = 13 cm. A ball of mass 50 g is put in front of the spring, and the spring is released. Calculate the speed of the ball (in %3D %3D %3D m/s) as it comes out of the barrel. Ignore friction inside the barrel.

- Please show your complete solution. Thank you! A fluid of 700 kPa with a specific volume of 0.025m^3 and a velocity of 175 m/sec enters a device. Heat loss from the device by radiation is 23 kJ/ kg. The work done by the fluid is 465 kJ/ kg. The fluid exits at 136 kPa and 0.94 m^3/kg and 335 m/sec. What is the change of internal energy?arrow_forwardQuestion 2 Water flows through a pipe at an average temperature of T = 50°C. The inner and outer radii of the pipe are ri = 6 cm and r2 = 6.5 cm, respectively. The outer surface of the pipe is wrapped with a thin electric heater that consumes 300 W per m length of the pipe. The exposed surface of the heater is heavily insulated so that the entire heat generated in the heater is transferred to the pipe. Heat is transferred from the inner surface of the pipe to the water by convection with a heat transfer coefficient of h = 55 W/m2 . °C. Assuming constant thermal conductivity and one-dimensional heat transfer, express the mathematical formulation (the differential equation and the boundary conditions) of the heat conduction in the pipe during steady operation and obtain temperature distribution in pipe.arrow_forwardThis example focuses on thermodynamicsarrow_forward
- Fluid mechanics The piston-cylinder unit contains a large amount of 20 atm and 0.04 m² of liquid. The liquid expands reversibly according to the law pv' = Cuntil its volume reaches twice its initial value. The liquid is then cooled again under constant pressure until the piston returns to its starting position. Now heat is applied reversibly while the piston is blocked until the pressure rises to the initial value of 20 atmospheres. Calculate the network formed by the liquid. Assume liquid means fluidarrow_forwardNitrogen gas flows through a compressor and a heat exchanger as shown in the figure below. All the provided properties at the inlets and outlets of both devices are shown. Nitrogen is modeled as an ideal gas. A separate cooling stream of Helium, also modeled as ideal gas, flows through the heat exchanger to lower the temperature of nitrogen. Assume that both devices are perfectly insulated and both gasses have constant specific heat values: Cpo of nitrogen = 1.042 kJ/kg. K) and Cpo of helium = 5.193 kJ/kg.K) A.
