Determine the entropy change if the volume is insulated
An impeller provides 20 kJ of work to the air contained in a 0.15 m3 rigid volume, initially at 200kPa and 10°C. Determine the entropy change if the volume is insulated.

A brake system applies a resistive torque of 25 N. How many revolutions will occur if a 300 kg solid wheel of diameter 0.25 m is slowed from 300 rpm to 0 rpm?
An X-ray machine accelerates electrons over a 300kV potential difference. The current is 1mA and the efficency of X-ray production in the anode is 0.01%. If the average energy of the emitted photon is 100keV, how many photons are emitted per secon
An air standard diesel cycle has a compression ratio of 20 and the heat transferred to the working fluid per cycle is 1800 kJ/kg. At the beginning of the compression process, the pressure is 0.1 MPa and the temperature is 15°C.
Calculate the steady rate of entropy production, s& (kJ/K/s), by the power unit & by the refrigeration unit. Entropy production is not a good thing. Find the amount of unnecessary or lost power = TATM * s& (kW).
Find the A) centripetal and B) total acceleration magnitude of a particle moving on a circle of radius 0.70 m, if its angular speed is 37.0 rpm and its tangential acceleration is 4.9 m/s^2.
Heating up water for your morning shower provides an excellent example of heat exchange (and mixing that you control). Consider the cold water (Cp = 4.18kJ/kg°C) leading to your shower enters a counter--flow heat exchanger at a rate of 0.
The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -2.69 rad/s. The axis of rotation for this unit is the same as that for the separate disks. What is th
