do solve this as soon as possible.its very imp for my exam.

Figure 1 2. Consider the expansion of flow through multiple pipes into the header (refer to Fig. 1). There are 50 number of steel tubes of inside diameter dp=0.025m of length L=1m. The diameter of header is Dh=0.25m. The average velocity of a Newtonian incompressible fluid (=1000kg/m3, =0.001Pas(kg/ms)) through each steel tube is u0=0.5m/s. (i) Derive an expression of P across section 1-2. Assume that the pressure at section 1 is uniform across the cross-section. (ii) Derive an expression for frictional loss (dissipation) per kg fluid flowing between section 1 and 2. (iii) The temperature of the fluid entering section 1(T1) is 30C and the temperature of the fluid leaving section 2(T2) is 50C. What is the rate of heat added per unit mass? The heat capacity of water is 4187J/(kgK).6+6+6=18 Figure 1 2. Consider the expansion of flow through multiple pipes into the header (refer to Fig. 1).
