Shortage of liquid oxygen could impact Space Coast launches

SOLVED: A rocket with liquid hydrogen (LH2) and liquid oxygen (LOX). Mass flow rate of LH2 and LOX are 1 kg/s and 15 kg/s. Control volume Density of product gas HO at exit is 0.5 kg/m^3. Cross-sectional area of exit is 0.2 m^2. H2 1 kg/s - Q. What is the velocity of the working fluid at exit? 15 kg/s (Please use consistent units!)Ae = 0.2 m^2Pe = 0.5 kg/m^3Combustion gas.

SOLVED: According to Torricelli's Law, the rate of liquid flow from an orifice is equal to dV/dt - 4.8AoVh, where h is the height (in feet) of the liquid above the orifice, Ao is the area of the orifice, V is the volume of the liquid, and t represents elapsed time (in seconds). If a cylindrical tank with a height of 9 ft and a base radius of 4 ft is filled with a liquid that is draining through a small circular hole (radius 1 in) in its base, how many minutes does it take for the tank to empty?a
