Which of the following statements are correct with respect t

Which of the following statements are correct with respect to the derivation of the momentum equation? (Select all that apply.) Reynolds Transport Theorem is applied to Fick\'s law. The extensive property is momentum. The intensive property is mass. The velocity is assumed to be uniformly distributed across each inlet and outlet. The net momentum flow is the \"ins\" minus the \"outs\". The net force is the sum of forces acting on the matter inside the CV. When making a force diagram (FD) and momentum diagram (MD) to set up the equations for a momentum equation problem, which of the following elements should be in the FD and which should be in MD? Each mass stream with product m_0v_0 or product m_iV_i crossing a control surface boundary. FD/MD Reaction forces required to hold walls, vanes, or pipes in place. FD/MD Weight of a solid body that contains or contacts the fluid. FD/MD Weight of the fluid. FD/MD Pressure force caused by a fluid flowing across a control surface boundary. FD/MD The balloon rocket is held in place by a force F. The pressure inside the balloon is 101.8 kPa abs, the nozzle diameter is 1.0 cm and the air density is 1.2 kg/m^3. Find the nozzle exit velocity v and the force F. Neglect friction and assume the air flow is inviscid and irrotational, the atmosphere pressure is 101.3 kPa abs.

Solution

As per chegg policy, question 1 can be answered

extensive property depends on mass of system, Since momentum depends on mass ,it is extensive property.

Mass is extensive property.

The momentum flow is out minus in.

So statements a,b,d,f are correct.
