Question

Consider a heating process where 180-liter liquid chemical material is heated from 25°C to 75 °C by a saturated steam condensing at T_sat = 127 °C, flowing through a horizontal
tube of 15 mm diameter and 17 m length. Assuming the liquid chemical material is an infinite and quiescent, calculate the initial heat transfer rate of chemical materials.
? = 1200 kg/m³; c = 2100 J/kg.K; k = 0.24 W/m.K; ? = 4 x10^-6 m²/s; Pr = 12; and ?= 0.002 K^-1
