Q: 1h). 2p) Which one is valid among the following statements regarding uniform-fl

In a uniform or steady flow control volume device,1)The volume, mass, total energy of the control volume remains constant with time. 2) In uniform flow, fluid propertie remains constant wrt time which means fluid flow at any inlet or exit is uniform and steady and the fluid properties do not change with time or position over cross-section of inlet or exit. Therefore ,(A),(B) ,(D) are correct statements.
