Ethyl alcohol is in a 310 mm-diameter tank at an initial height of 2 m. The ethyl alcohol exits the tank through a 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. What is the approximate actual velocity in m/s coming out of the orifice at ethyl alcohol height of 1 m

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
