Question: a what are the three main conservation equations that are...

Question details

a) What are the three main conservation equations that are used to describe general fluid flow and what is the physical importance of each of these equations? [4 marks] b)What equation is shown below? ou ul 2l What is it trying to represent physically? Explain the significance of each term or groups of terms (when appropriate) in this equation [6 marks] c) A pipe is bent in the horizontal plane in such a way that the angle between the inlet and the outlet sections of the pipe is 45°. The inlet diameter of the pipe is 0.3 m and the outlet diameter is 0.15 m. The mass flow rate of air through the pipe is 4 kg/s and air density remains constant throughout at 1.2 kg/m3. Calculate the force on the pipe bend exerted by the air (in magnitude and direction) if the upstream static pres- sure of the air is 105 N/m2. [10 marks]
