The olympias is a reconstruction of a trireme, a type of greek galley ship used over 2000 years ago. the power p (in kilowatts) needed to propel the olympias at a desired speed s (in knots) can be modeled by this equation: p = 0.0289s3 a volunteer crew of the olympias was able to generate a maximum power of about 10.5 kilowatts. what was their greatest speed? start a new thread

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.
