Air enters a tank through an area of 0.2 ft2 with a velocity of 15 ft/s and a density of 0.03 slug/ft3. Air leaves with a veloci

ty of 5 ft/ s and a density equal to that in the tank. The initial density of the air in the tank is 0.02 slug/ft3. The total tank volume is 20 ft3 and the exit area is 0.4 ft2. Find the initial rate of change of density in the tank.

Consider the smoothie example given in class: Write down the production function of Tutti Frutti Smoothie example given in class
mart [117]

Answer:

Production Function : TFSq = f { ingredient 1 ...... ing. i }

Increasing/ Constant/  Increasing Returns to Scale :

Output change > / = / < Input change respectively

Explanation:

Production Function is the relationship between production inputs & outputs, given technology. It denotes the maximum output that can be generated with given inputs.

Tutti Frutti Smoothie [TFS] quantity = Function of {Ingredient1.....ingredient i}

Returns to Scale represents change in output when all inputs change in same proportion.

  • Constant Returns to Scale [CRS] : Output Change = All inputs change
  • Increasing Returns to Scale [IRS] : Output Change > All inputs change
  • Negative Returns to Scale [NRS] : Output Change < All inputs change

When all inputs (ingredients) change by same proportion i.e get twice 2X :- If output of Tutti Frutti Smoothie increases by > 2X  i.e 3X - IRS.  If it increases equal ie 2X - CRS. If it increases lesser i.e 1.5X - CRS.
