4) The heat transfer correlation for a liquid flowing over a single cylinder is given by the following equation for Nusselt number (Nu): Nu-h D/k=(0.506 Re5+ 0.00141 Re) Pro where hheat-transfer coefficient D diameter of cylinder kthermal conductivity of cylinder Re Reynolds number -D v p/u Pr Prandtl number Cp k viscosity of liquid v velocity of liquid C, specific heat capacity of liquid p density of liquid The above equation, in association with the Chilton-Colburn analogy, can be used to predict the mass-transfer coefficient for a cylinder. Estimate the mass-transfer coefficient k at 300 K for the dissolution of sodium chloride from a cast cylinder (diameter 1.5 cm) made of solid sodium chloride (NaCl) and placed perpendicular to a flowing stream of water at a velocity of 10 m/s. DATA: Binary liquid diffusivity (DAB) at 291 K-1.26 x 10 m/s Viscosity of water at 291 K = 1.073 x 10 Pas Viscosity of water at 300 K=8.76 x 10 Pas Density of water-996 kg/m 4) The heat transfer correlation for a liquid flowing over a single cylinder is given by the following equation for Nusselt number (Nu): Nu-h D/k=(0.506 Re5+ 0.00141 Re) Pro where hheat-transfer coefficient D diameter of cylinder kthermal conductivity of cylinder Re Reynolds number -D v p/u Pr Prandtl number Cp k viscosity of liquid v velocity of liquid C, specific heat capacity of liquid p density of liquid The above equation, in association with the Chilton-Colburn analogy, can be used to predict the mass-transfer coefficient for a cylinder.
