An open tank, 10 ft in diameter, containing benzene at 25 C is exposed to air.
Question:
An open tank, 10 ft in diameter, containing benzene at 25οC is exposed to air. Above the liquid surface is a stagnant air film 0.2 in. thick. If the pressure is 1 atm and the air temperature is 25οC, what is the loss of benzene in lb/day? The specific gravity of benzene at 60οF is 0.877. The concentration of benzene outside the film is negligible. For benzene, the vapor pressure at 25οC is 100 torr, and the diffusivity in air is 0.08 cm2/s.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
