An air stream dot{M}_L = 5.5  kg/s, cp_L=1 kJ/(kgK) is to be heated in a plate heat exchanger from θ_L′=20∘C ′ to θ_L′′=150∘C. For this purpose, a flue gas stream dot{M}_R = 7.22, cp_R=1.1 kJ/(kgK) with a temperature of θ_R′=300∘C is available. The overall heat transfer coefficient is k=15 W/(m^2*K).
What is the required heating surface AAA if the fluid streams are arranged in counterflow?

You would like to drink a cup of very hot coffee with milk early in the morning, but you
are in a hurry and have only 5 minutes until you have to leave for work. At which time
after brewing should you add the cold milk to the coffee and stir in order to decrease the
temperature of the mixture as much as possible:
a) 0 minutes (immediately),
b) 2 minutes, or
c) 4 minutes?
Suppose that the stirring can be done instantaneously and that you need the last one
minute for drinking.

brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature
0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat
capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).

Please enter only the letter of the corresponding answer

  • p2 = p1 * (V1/V2)^gamma
  • gamma= 1.4
