 So, we are talking about the assumptions that we had in Bernoulli's theorem. So, the first assumption is that it is in viscous fluid. If you consider it to be in viscous and if you consider it to be laminar flow and second assumption compressible. So, if fluid if it is coming fluid dynamics, if G is more of a viscosity then you can do by direct it as force and the substitute this value on this equation you will get. So, the fluid which is solid is moving the fluid inside the fluid which is quantifying these two things inside where it is minus sigma into G is equal to 0. So, from
