Answer 1

Tints for frow, US teady Flad = seady flow is defined as that type of flow in which the fluid Characteristics like velocity, pressure, density. et. at a point do not change with time. Steady Unsteady flows it is that type of flow, in which the velocity, pressure at a point changes with respect to time. in Flow patterns Steady of density flow eft A Steady flow with uniform velouly (at A at time to velocity is a & at time 627 velocity is u] Steady flow with Changing velocity. [at A, at time to & to the velocity is w t F t unsteady flow flow will be sanitar as steady flow, but at to velocity is 9 & at to velocity is vi riii, Mathematically, steady flow, al =0 co St. dt орого Hoyo20 ot no Yozo e proteze to Ho%20 where (no 190, 20) is fixed point in fluid field Matthemah'celly for unslecely' flow, ou now to get CUJ Applicahon: Steady flow flow of water with Constant discharge through a pipeline.
