Question

In order to improve business, the Wiessherr Biergarten in Augsburg, Germany began a new gimmick promotion, the bier fountain. The patron steps on a floor-mounted bellows which forces a column of beverage through a nozzle and up into the air where the patron can consume a mouthful. It takes some practice to apply just the correct force in order to get the column to end right at mouth height for the optimal consumption. Being a Chemical Engineer, Gnter decided to calculate the pressure needed on the bellows. If the average Germans mouth is located 140 cm above the level of the nozzle, how much pressure must be applied to the bellows so that the column of beverage (density = 1 g/cm3) just reaches mouth height?

Explanation / Answer

use bernouli theorem p+0.5rhov^2= Po+rho *g*h where rho=density of the beer here h=140 cm and v=velocity required
