The mоst cоmmоn cаncer in young, white men аged 20 to 34 yeаrs is:
Refrigerаnt enters the cоndenser оf а refrigerаtiоn system at 700 kPa and 30°C at a rate of 0.015 kg/s. Refrigerant leaves the condenser at the same pressure as a saturated liquid. The rate of heat absorbed from the cooled space is 2 kW. Find (a) the power input to the compressor, (b) the COP of the refrigerator. [25 points] 2. A rigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 4 MPa. Now the valve is opened, and steam is allowed to flow into the tank until the pressure reaches 4 MPa, at which point the valve is closed. If the final temperature of the steam in the tank is 500°C, determine the temperature of the steam in the supply line. [water remains superheated throughout the process] [perform linear interpolation when necessary] [25 points] 3. A heat pump receives heat from a lake that has a temperature of 353 K and supplies heat into a boiler. The input of the boiler is saturated liquid water and the exit is saturated vapor both at 350 kPa. The heat pump requires a power input of 2.5 MW. The COP of the heat pump is 60% of a Carnot heat pump COP. What is the mass flow rate of the water? [25 points] 4. A heat exchanger is used to cool an air flow from 527°C to 87°C at 1 MPa. Coolant water enters the heat exchanger at 15°C at 0.1 MPa and leaves as saturated vapor. Each line has a constant pressure. Find the ratio of flow rates
