6. (3 points) A water-based heating system is shown in Figure 5. A pump exerts a constant pressure difference between its inlet and outlet, ΔΡ-12 psi, to circulate hot water across 2 distinct paths. One path contains a single radiator that can be modelled as a pipe with an effective resistance to water flow of Ri-4x 107 kg-m-4 . s-1. The other path has two radiators with effective resistances to water flow given by R2-5x 107kg. m-4-S-1 and R3 3...

Water flows steadily through a curved duct that turns the flow through angle = 1359, as shown in Fig. 3. The cross-sectional area of the duct changes from A1 = 0.025 m’ at the inlet to Az = 0.05 m² at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as B - 1.01 at the duct inlet and B = 1.03 at the...
