Question

In the figure below, air is flowing incompressibly through the horizontal pipe.a) How do the pressures at points A and B compare? b) How do the velocities of the fluid at points A and B compare? c)How do the flow rates at points A and B compare? I've been having trouble with this homework assignment and am unsure how to explain.

Answer #1

a) using Bernoulli's theorem, Pressure depends inversely on velocity of liquid and velocity depends inversely on area of cross section hence it is clear that pressure depends directly on area of cross section, so pressure is moreleid > 낭>나 Ueloc do, move at 60mm kih at A and less at B.

    Water flows through a horizontal pipe similar to the pipe in DL. It enters the pipe at point (1), then leaves the pipe at point (2), which is open to the atmosphere. The height of the water in each vertical column is below. Now suppose that the length of this pipe is doubled. The pressure at point (I) is the same as before. Point (2) is still open to the atmosphere. Water is again allowed to flow from point (1)...

    In a refrigeration cycle showed in the figure below, refrigerant 134 was used as the working fluid to remove 1. heat from the cooling chamber (condenser). The refrigerant was flowing through a pipe having inside diameter 11mm during the whole cycle. Just after expansion, the refrigerant was found to be a mixture of liquid and vapor in which liquid is found to be 60%. The mixture was flowing with a velocity of 164 ft/sec at pressure of 0.2 Mpa. Calculate...
