Water enters a 2-cm-diameter and 3-m-long tube whose walls are maintained at 100°C with a bulk temperature of 25°C and volume flow rate of 3 m³/h. Neglecting the entrance effects and assuming turbulent flow, the Nusselt number can be determined from Nu = 0.023 Re^0.8 Pr⁰⁴. The convection heat transfer coefficient in this case is

(a) 4140 W/m² · K

(b) 6160 W/m² · K

(c) 8180 W/m² · K

(d) 9410 W/m² · K

(e) 2870 W/m² · K
(For water, use k = 0.610 W/m · K, Pr = 6.0, μ = 9.0 × 10^-4 kg/m · s, ρ = 1000 kg/m³)
