Show transcribed image text A garden hose attached with a nozzle is used to fill a 10 gallon bucket. The inner diameter of the hose is 2 cm, and it reduces to 0.8 cm at the nozzle exit. If it takes 50 s to fill the bucket with water, determine (a) the volume and mass flow rates of water (in ”L/s” and ”kg/s”) through the hose, and (b) the average velocity (in ”m/s”) of water at the nozzle exit. Solution A garden hose is used to fill a water bucket. The volume and mass flow rates of water and the exit velocity are to be determined. Assumptions (1) Water is an incompressible fluid. (2) Flow through the hose is steady. (3) There is no waste of water by splashing. Properties The density of water is: p =1,000 kg/m^3 =1 kg/L
