In an experimental study, peach purée is being concentrated in a continuous vacuum evaporator at a rate of 65 kg/hr. the feed material has a temperature of 15℃ and a total solids content of 10.9%. a product of 40.1% total solids is withdrawn at a temperature of 40℃, and condensate leaves the condenser at 35℃.
a) calculate the flow rate of the product and condensate streams.
b) if steam condensing 120℃ is used to supply the heat of evaporation, calculate the steam consumption in kg/hr. the specific heat of the solid material is 2.09 kj/kg. k.
c) cooling water enters the condenser at 20℃ and leaves at 30℃. calculate the cooling water flow rate.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
