Gas speed equation
WebUsing the equation of drag force, we find mg = 1 2ρCAv2. Solution The terminal velocity vT can be written as vT = √2mg ρCA = √ 2(85kg)(9.80m/s2) (1.21kg/m3)(1.0)(0.70m2) = 44m/s. Significance This result is consistent with the value for vT mentioned earlier. The 75-kg skydiver going feet first had a terminal velocity of vT = 98m/s. WebThe average molecular speed can be calculated from the Maxwell speed distribution as = / ... This equation is known as Graham's law of effusion. The effusion rate for a gas depends directly on the average velocity of …
