Question 17
XE-GNAT2 marksNeeds review
A mixed fruit beverage with 12 °Brix having specific heat of 4298 J kg⁻¹ K⁻¹ is being heated from 30 °C to 95 °C for pasteurization at a flow rate of 1000 L h⁻¹ in a tubular heat exchanger. Steam at 100 °C is used as heating medium which is converted into condensate at 100 °C. If the density of beverage is 1075 kg m⁻³ and the latent heat of steam at the given temperature is 2257 kJ kg⁻¹, the mass flow rate of steam (kg min⁻¹) is ______ (round off to 2 decimal places).
