The Seider and Tate equation for calculating convection heat transfer coefficients in pipes employs a viscosity correction factor, (wb)0.14, where b is the viscosity of the fluid at the bulk average temperature, and W is the viscosity of the fluid at the wall temperature. For a fluid with a bulk viscosity of 857mPas and a wall viscosity of 586mPas, calculate the percentage increase in the calculated heat transfer coefficient resulting from applying this correction factor. Give your answer, as a percentage, to 1 decimal point
