A) \[\frac{v{{R}^{2}}}{{{n}^{2}}{{r}^{2}}}\]
B) \[\frac{v{{R}^{2}}}{n{{r}^{2}}}\]
C) \[\frac{v{{R}^{2}}}{{{n}^{3}}{{r}^{2}}}\]
D) \[\frac{{{v}^{2}}R}{nr}\]
Correct Answer: B
Solution :
Key Concept During the streamline flow of viscous and incompressible fluid through a pipe varying cross-section, the product of area of cross section and normal fluid velocity (Ay) remains constant throughout the flow. Consider a cylindrical tube of a spray pump has radius R, one end having n fine holes, each of radius r and speed of liquid in the tube is v as shown in figure.You need to login to perform this action.
