The handling of gasoline is a routine occurrence. Yet spills can happen from time to time and vaporization occurs. Under certain conditions, the gasoline vaporized exceeds the TLV of 300.0 ppm. The TLV is called the Threshold Limit Value, and is the maximum safe condition for human exposure. A spill of gasoline occurs such that a pool 2.00 m in diameter is formed in an area that has a ventilation rate of 100.0 m3/min. If the air velocity is 3.00 m/s, what is the steady state concentration (in ppm) of gasoline fumes in the enclosed area? Use a diffusivity of gasoline in air of 10-5 m2/s, assume that the temperature is 25.0°C, and assume the pressure is 1.00 atm. The vapor pressure of gasoline (MW = 94.0) at 25.0°C is 31,700 Pa.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
