A 410 turn solenoid of length 39.5 cm and radius 2.80 cm carries a current of 4.90 A. Find the following. (a) the magnetic field strength inside the coil at its midpoint mT (b) the magnetic flux through a circular cross-sectional area of the solenoid at its midpoint

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
