CHEE 3363---Fluid Mechanics Assignment 11 (Due on Wednesday, Nov. 17) Pro 7.30 The diameter, ° , of the dots made by an ink jet printer depends on the ink viscosity, ± , density, ? , and surface tension, ? , the nozzle diameter, ² , the distance, ³ , of the nozzle from the paper surface, and the ink jet velocity, ´ . Use dimensional analysis to find the Π parameters that characterize the ink jet s behavior. Pro 7.56 The fluid dynamic characteristics of a golf ball are to be tested using a model in a wind tunnel. Dependent parameters are the drag force, µ ² , the lift force, µ ³ , on the ball. The independent parameters should include angular speed, , and the dimple depth, ° . Determine suitable dimensionless parameters and express the functional dependence among them. A golf pro can hit a ball at ´ = 240 ·? ? and = 9000 ¸¹º . To model these conditions in a wind tunnel with maximum speed of 80 ·? ? , what diameter model should be used? How fast must the model
