For most gases at standard or near standard conditions, the relationshipamong pressure, density, and temperature is given by the perfect gasequation of state: p = ρRT, where R is the specific gas constant. For airat near standard conditions, R = 287 J/(kg · K) in the International System of Units and R = 1716 ft · lb/(slug · ◦R) in the English Engineering System of Units. Using the above information, consider the following two cases: a. At a given point on the wing of a Boeing 727, the pressure andtemperature of the air are 1.9 × 104 N/m2 and 203 K, respectively.Calculate the density at this point.b. At a point in the test section of a supersonic wind tunnel, the pressureand density of the air are 1058 lb/ft2 and 1.23 × 10−3 slug/ft3,respectively. Calculate the temperature at this point.
Here, a liquid's density is to be determined by a 1-cm diameter cylindrical hydrometer whose division marks are non visable. The hydrometer is first dropped in water, and the water level is marked. The hydrometer is then dropped into the 'liquid x', and it is observed that the mark for water has risen 0.85 cm above the liquid–air interface. In this case, the height of the originalwater mark is 12.7 cm. As such, how would I determine the density of the liquid?
