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).
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.
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.
