A machine oscillates in simple harmonic motion and appears to be well modeled by an undamped single-degree-of-freedom oscillation.
Its acceleration is measured to have an amplitude of 10,000 mm/s 2 at 8 Hz. What is the machine's maximum displacement?
A closed, rigid tank is filled with a gas modeled as an idea gas, initially at 27 degrees C and a gage pressure of 300 kPa. The gas is heated, and the gage pressure at the final state is 367 kPa. Determine the final temperature, in C. The local atmos..
Determine whether fouling has occurred during the service period. If so, calculate the fouling factor, R"f (m2 · K/W).
a projectile is launched from the ground with v0100fts at t0 theta060 degrees. determine the time t when the velocity
1000 kg/h of milk is heated in a heat exchanger from 45oC to 72oC. Water is used as the heating medium. It enters the heat exchanger at 90oC and leaves at 75oC. Calculate the mass flow rate of the heating medium, if the heat losses to the environment..
How an electronic controller could be included in the circuit to control the sequence of cylinderoperations - State the sequence in which the cylinders operate on the operation of the startvalve.
Water is contained in a 0.2 m3 vessel at 200 C. The mass of water in the vessel is measured to be 2 kg. Determine (a) the pressure in the vessel, (b) the enthalpy, h, of the water in kJ/kg, (c) the mass and volume of vapor in the vessel.
A balloon filled with helium can carry 2 people each of a mass of 85 kg. the balloon materials and the carriage weigh 980 N. if the acceleration when the balloon is first released is 16.40 ft/s^2, calculate the volume of the balloon in m^3. The buoya..
