The contents of a tank are to be mixed with a turbine impeller that has six curved blades. The diameter of the impeller is 6 ft. If the water temperature is 30C and the impeller is rotated at 50 rev/min, what will be the power consumption in Watts? If the volume of the tank is 1000 ft3, what is the G value (in s-1)? Is the G value sufficient for rapid mixing? Repeat the calculations for 10C. If you want the same G value for 10C as you had at 30C, what rpm and power input do you need to use?
