Chapter 8, Problem 8.128EP

The air conditioner in a house or a car has a cooler that brings atmospheric air from 30 degree Celsius to 10 degree Celsius, both state at 101 kPa. For a flow rate of 0.75 kg/s find the rate of heat transfer

i need the answer quickly

QUI A piston-cylinder device with a set of stops initially contains 300 g of steam at 1000 Kpa and 400 C. Find the work if the final state IMpa and 250 C, and work if the position of the stops corresponds to 60% of the initial volume and also find the temperature at the final state if P-500Kpa Steam 300 g 1000 Kpy 400°C e

Please help..

The number is 9

of air at 300 K and 150 kPa. It's now heated in a two- Q: A piston cylinder contains 1.5 step processes: first by a constant volume process to 1000 K second a constant pressure process to 1500 K. find the heat transfer for this processes.

3. A heat sink for computer server absorbs all the heat generated and cools down by air flow. The air flow is 15 liter/s. The density of air near the heat sink is 1.25 kg/m³. The specific heat of air at constant pressure is 1,010 and the room air is 20°C. can handle. J/kg-°C. The temperature at the heat sink is 50°C, Find the server (heat) power in Watt that the heat sink

A cycle HE does 60kJ of work per cycle. If the efficiency of the heat engine is 60%. The heat rejected per cycle is.
