A storage tank for Ethanol is shown above. If the tank is empty, and at an ethanol height in tank of 20 feet, the pressure is 17.1 psi pressure, when the tank is full, (means ethanol height in tank is 40feet)? r control equation should be used? the pressure is 10.3 psi. What would be the pressure, when the tank is full, (means ethanol height in tank is 40feet)?

Biochemical Engineering mainly deals with the design, construction, and advancement of unit processes that involve biological organisms (such as fermentation) or organic molecules (often enzymes) and has various applications in areas of interest such as biofuels, food, pharmaceuticals, biotechnology, and water treatment processes.
