An air compressor takes in air at 100kPa, 17°C and delivers it at 1 MPa, 600K to a constant pressure cooler which it exits at 300K. Find the work performed and heat transfer, both (kJ/kg).
In a 150 MW steam turbine unit operating on an enhanced Rankine cycle, steam is delivered from the boiler to the high pressure turbine at 15 MPa and 500° C.
A particle (m = 3.0 µg, q = 5.0 µC) moves in a uniform magnetic field given by (60j)mT. At t = 0 the velocity of the particle is equal to (30j - 40k) m/s. The subsequent path of the particle is:
