Need help with question adef
Figure QaIn an industrial plant, litre plastic bottles are filled with orange juice. The filling process is achieved by draining the juice from a storage tank into the bottle through a straight circular pipe connected to the bottom of the tank see Figure Qa The juice density and dynamic viscosity are and Pas, respectively. The height, of the storage tank is The tank is open to the atmosphere, and it has a circular cross section with a diameter The level of juice in the tank at a time, is denoted as and, at the time the juice level, is equal to two third of the tank height. The pipe diameter and length are and respectively.
a Calculate how many juice bottles can be filled during the process. Assume that the filling process ends when the juice level reaches the bottom of the tank.Answer
b Demonstrate that the juice average velocity at the outlet of the pipe, can be expressed as
Assume a turbulent flow and neglect the effects of friction.
c Demonstrate that the time, taken for the level of juice in the tank to fall from to is given by the following expression:
d Calculate how long it takes for the level of juice in the tank to reach the bottom of the tank namely, how long it takes to fill the number of bottles calculated at point ahr
e Show that the flow at the outlet of the pipe is turbulent at any time during the process.
f Assume that the storage tank is pressurised. By denoting as the tank pressure, determine the new expressions for the juice average velocity at the outlet of the pipe, and the time, taken for the level of juice in the tank to fall from to
