Assume that a pt-100 sensor is used for a temperature measurement in a control process. the distance between the sensor and the controller is 5 meters and the sensor has been connected with a 0.50 mm diameter copper cable. how many degrees of error does food then measure due to the voltage drop across the connection conductors? comma has the resistivity 1.67 * 10 ^ -8 ohm

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.
