Multi-processors computer operates in a server room in a building of weather station located in the mountains at altitude of 3400 m computer is cooled by two 2 w fans located at the outlet from chassis. the thermal power of each processor is 65 watt. the temna pressure in the server room are 25°c and 66.63 kpa, respectively. the temperature and air velocity at the outlets from the chassis are so 70.6 m/min, respectively, while diameters of fans are 0.1 m. determined the number of processors in the computer. neglect heat in surroundings from the computer and the change in kinetic energy of cooling air as well as assume no variation in the statie nr may be treated as an ideal di-atomic gas with gas constant 287 j/(kgk).

Y=‐1x + 7 if y has a value of ‐24 what is the value of x?

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
