The system is released from rest with the cable taut. For the friction coefficients πs = 0.25 and πk = 0.20, calculate the acceleration of each body and the tension T in the cable. Neglect the small mass and friction of the pulleys.
The bucket has weight W. Determine the tension developed in each cord for equilibrium.
The packed tower was 30 cm in diameter with sampling ports located at packing depths of 0,2,4,6,8,10, and 12 meters. The loading of water to the tower was 0.039 m^3/(m^2/s), and the temperature of groundwater was 10 degrees celcius.
The cylindrical wall of the tank is 6mm thick, has a 600mm inside diameter, and is made of steel with E = 200 GPa and v = 0.30. Determine the pressure in the tank indicated by a strain gage reading of 280*10^-6 in/in.
Determine the power input to the compressor and the rate of heat rejection by treating the mixture (a) as an ideal gas and (b) as a non-ideal gas and using Amagat's law.
Helium gas is compressed isentropically from 1 bar and 25 C to a pressure of 10 bar. The temperature of Helium after the compression is A) 25 C B) 63 C C) 250 C D) 384 C E) 476 C
Prepare an engineering report for the following abstract. This report is based on the four tests which were carried out on the laboratory to help gain concepts in Highway Engineering.
plot the exit pressure, the exit velocity, and the mass flow rate through the nozzle versus the back pressure Pb for 6.0 ≥ Pb c ≥ 3.0MPa. Treat the steam as an ideal gas with k =1.3, cp= 1.872 kJ/kg · K, and R =0.462 kJ/kg · K.
Determine the mass of the earth knowing that the mean radius of the moons orbit about the earth is 238.910mi and that the moon requires 27.32 days to complete one full revolution about the earth
A stack gas at 1.1 atmospheric pressure has a mixture below. what will be the change in partial pressure of carbon dioxide if the gas temperature is lowered from 2000 degrees K to 1000 degrees K
Also find the magnitude of the force on the pin at A. Neglect any acceleration of the center O of the spacecraft.
Saturated liquid water is in an adiabatic compressor with inlet and outlet pressures of 100 kPa and 1 Mpa. The isentropic efficiency is 85%. Find the work input (kj/kg) and entropy generation (kj/ kg K).Do the same for saturated vapor steam in an adi..
