A car air conditioning system takes air at 35 °C from the surrounding atmosphere and cools it down to 15 °C in a heat exchanger from which heat is removed by an ideal refrigeration cycle using refrigerant 134a. The condenser pressure is 1.2 MPa and the evaporator pressure is 0.2 MPa. If the car engine can supply 2 kW of power to run the air conditioner what is the maximum mass flow rate of cold air that can be supplied

QUESTION 4 (15 marks) Below is a schematic of a car air conditioning system that uses R-134a as its refrigerant. Here we will analyze the system under the case of driving through a very hot environment of 40 °C. The interior of the car is kept at 20 °C. Refrigerant leaves the compressor at 1.6 MPa absolute and leaves the condenser as a saturated liquid. The evaporator operates at 400 kPa absolute and the refrigerant leaves as a saturated vapour....

Exhaust gas emitted by a particular automobile contains 20 g of carbon monoxide (CO) for every km driven. If this car is driven 30 km, how much carbon monoxide will have been emitted, and what would be the volume of the carbon monoxide after it cools to 25°C at a pressure of 1 atm? Assume carbon monoxide (and the atmosphere) acts as an ideal gas. Per km of travel, what volume of air could be polluted by the carbon monoxide...
