Explanation Write the relation between the velocity at inlet and velocity at outlet using the continuity equation. Q = A 1 V 1 = A 2 V 2 (I) Here, the area of the outlet is A 2 , the velocity of the inlet is V 1 , the velocity of the outlet is V 2 , the diameter of the pipe is D 1 , and discharge is Q . Write the expression to determine the 9 holes in the grill hole area ( A 2 ) . A 2 = 9 × π 4 D 2 2 (II) Here, the diameter of the hole is D 2 . Write the Bernoulli's equation for the inlet and outlet streams for points (1) and (2). p 1 γ + V 1 2 2 g + Z 1 = p 2 γ + V 2 2 2 g + Z 2 (III) Here, inlet pressure is p 1 , outlet pressure is p 2 , specific weight of air is γ , acceleration due to gravity is g , the initial datum is Z 1 , and the final datum is Z 2 . Conclusion: Substitute 0 for V 1 , 0 for Z 1 and Z 2 , ρ g for γ , and 0 for p 1 in Equation (III). 0 γ + 0 2 g + 0 = p 2 ρ g + V 2 2 2 g + 0 p 2 = − ρ × V 2 2 2 g (IV) Substitute 0

(b) A steel 'hot rolled structural hollow section' column of length 5.75 m, has the cross-section shown in Figure Q.5(b) and supports a load of 750 kN. During service, it is subjected to axial compression loading where one end of the column is effectively restrained in position and direction (fixed) and the other is effectively held in position but not in direction (pinned). i) Given that the steel has a design strength of 275 MN/m², determine the load factor for the structural member based upon the BS5950 design approach using Datasheet Q.5(b). [11] ii) Determine the axial load that can be supported by the column using the Rankine-Gordon formula, given that the yield strength of the material is 280 MN/m² and the constant *a* is 1/30000.
