Heat transfer coefficient in evaporatora 10 wt% naoh solution is concentrated to 40 wt% in an evaporator operating at 40 kpa. the feed enters the evaporator at a mass flow rate of 4200 kg/hr and a temperature of 21.1°c. the evaporator area is 1.12 m2. saturated steam at 110°c is used for heating. a)calculate the boiling point rise (bpr) in the evaporator; b)calculate the steam flow rate in kg/hr; c)calculate the overall heat transfer coefficient in units of w/(m2*k).

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
