Question

In a dairy processing plant, milk enters a 30 m long and 2 cm diameter tube at 60 ⁰ C and leaves at 57 ⁰ C. The total heat loss over the tube length is 381.15 W. The specific heat capacity, density, and viscosity of milk are 3.85 kJ kg ⁻¹ K ⁻¹ , 1020 kg m ⁻³ , and 1.20 cP, respectively. The Reynolds number for the flow is ______ (round off to the nearest integer). Given: π = 3.14 (NAT)
