Water at 10C ( = 999.7 kg/m 3 , = 1.307 10 3 kg/ms) is

Water at 10°C (ρ = 999.7 kg/m³, μ = 1.307 × 10^–3 kg/m∙s) is to be transported in a 5-cm-diamater, 30-m-long circular pipe. The roughness of the pipe is 0.22 mm. If the pressure drop in the pipe is not to exceed 19 kPa, the maximum flow rate of water is

(a) 324 L/min 

(b) 281 L/min 

(c) 243 L/min

(d) 195 L/min 

(e) 168 L/min
