Conservation of mass applies to steady systems, but not to unsteady systems.Question 6Select one:a.TRUEb.FALSEc.There is not enough information to give a definitive answer

Which of the statements are true?Group of answer choicesFor flow in a pipe, the velocity is the same across the pipe cross section.Mass flow rate can be defined as the multiples of density, pipe average velocity, and cross section area normal to the velocity.A volume flow rate is defined as the volume of the fluid flowing through a cross section per unit time.A mass flow rate into control volume is proportional to the velocity component parallel to the cross sectional area.Mass flow rate is defined as the amount of mass flowing through a cross section per unit time.

Which of the following statements is true about the law of conservation of mass?
