Air at 50 oC and 80 kPa enters the diffuser of a jet engine steadily with a velocity of 500 m/s. The inlet area of the diffuser is 0.4 m2. The air leaves the diffuser with a velocity that is very small compared to the inlet velocity. Determine the temperature (in oC) of the air leaving the diffuser.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
