On a hot summer day (95°F), you walk outside from an air-conditioned room (75°F) watching TV and begin jogging. Describe how your body reacts physiologically to the change in temperature. Be sure to include the following terms: set point, normal range, homeostasis, stimulus, sensor, input signal, integrating center, output signal, target and response (10 pts), include examples of tissues and organs that make up the sensor, input signal, integrating center, output signal, target (5 pts).

7.21 The Weather Channel reports that it is a hot, muggy day with an air temperature of 90°F, a 10 mph breeze out of the southwest, and bright sunshine with a solar insolation of 400 W/m2. Consider the wall of a metal building over which the prevailing wind blows. The length of the wall in the wind direction is 10 m, and the emissivity is 0.93. Assume that all the solar irradiation is absorbed, that the surroundings are at Tsur...

A window-mounted air conditioner supplies 19 m3/min of air at 15°C, 1 bar to a room. Air returns from the room to the evaporator of the unit at 22°C. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with Refrigerant 22 entering the compressor at 4 bar, 10°C. Saturated liquid refrigerant at 11.5 bar leaves the condenser. The compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 11.5 bar. Determine: (a) the compressor...

A window-mounted air conditioner supplies 29 m3/min of air at 15°C, 1 bar to a room. Air returns from the room to the evaporator of the unit at 22°C. The air conditioner operates at steady state on a vapor-compression refrigeration cycle with Refrigerant 22 entering the compressor at 4 bar, 10°C. Saturated liquid refrigerant at 9 bar leaves the condenser. The compressor has an isentropic efficiency of 70%, and refrigerant exits the compressor at 9 bar. Determine: (a) the compressor...
