Transcript

  • 1. BITS Pilani Pilani CampusLecture 13 – FIRST LAW ANALYSIS FOR FIRST-A CONTROL VOLUME
  • 2. CompressorA compressor receives 0.1 kg/s R-134a at 150 g kPa, -10oC and delivers it at 1000 kPa, 40oC. The power input is measured to be 3 kW. The compressor h h t t has heat transfer t air at 100 kP f to i t kPa coming in at 20oC and leaving at 25oC. How much is the mass flow rate of air? BITS Pilani, Pilani Campus
  • 3. Mixing ChamberIn engineering applications, thesection where the mixingprocess takes place iscommonly referred to as a ymixing chamber The T elbow of an ordinary shower serves as the T-elbow mixing chamber for the hot- and the cold-water streams. BITS Pilani, Pilani Campus

  • 11. Multi component systemsA modern jet engine has a temperature aftercombustion of about 1500 K at 3200 kP as it enters b ti f b t t kPa tthe turbine section, see state 3 Fig. P.6.100. Thecompressor inlet is 80 kPa 260 K state 1 and outlet kPa,state 2 is 3300 kPa, 780 K; the turbine outlet state 4into the nozzle is 400 kPa, 900 K and nozzle exit ,state 5 at 80 kPa, 640 K. Neglect any heat transferand neglect kinetic energy except out of the nozzle.Find the compressor and turbine specific work termsand the nozzle exit velocity.

  • 16. RefrigeratorA R-410a heat pump cycle (refrigerator) shown in Fig. P6.99 has a R-410a flow rate of 0.05 kg/s with 5 kW into the compressor. The following data are givenCalculate the heat transfer from the compressor, the heat transfer from the R-410a in the condenser and the heat transfer to the R-410a in the evaporator R 410a evaporator.
