Ethyl alcohol is in a 300 mm-diameter tank at an initial height of 1 m. The ethyl alcohol exits the tank through an sharp-edged orifice, which has a diameter of 2 mm and located at the bottom of the tank. The tank is open to the atmosphere. (a) State all assumptions. Include references and explanations as needed. (b) Sketch and define the control volume. (c) Derive and simplify the mass balance. (d) What is the approximate actual velocity in m/s coming out of the orifice at ethyl alcohol height of 0.5 m? (e) How long will it take to drain the tank completely in s?
