0 0 votes Consider the two-dimensional velocity field given by $\overrightarrow{V}=(5+a_{1}x+b_{1}y)\hat{i}+(4+a_{2}x+b_{2}y)\hat{j}$, where $a_{1}, b_{1}, a_{2}$ and $b_{2}$ are constants. Which one of the following conditions needs to be satisfied for the flow to be incompressible? $a_{1}+b_{1}=0$ $a_{1}+b_{2}=0$ $a_{2}+b_{2}=0$ $a_{2}+b_{1}=0$ Fluid Mechanics gateme-2017-set1 fluid-mechanics-and-thermal-science fluid-mechanics + – ♦Arjun 284 views answer comment Share Follow Add Sync Questions 0 reply Please log in or register to add a comment.
