Question

fluid flows at a steady rate through ten well behaved tank in series .a pulse of tracer is introduced into the first tank . at the time this tracer leaves the system , a maximum concentration of 100m mol and the tracer spread of 1 min is observed . if 5 more tanks are connected in series with the original ten tanks , what would be the maximum concentration of leaving tracer?. a) cmax =170.73m mol . b) cmax= 140.73mmol) cmax=220.73mmol d) cmax = 120.73mmol.​

Width of rectangle is 25 cm.

Step-by-step explanation:

Given :-

A wire bend in form of square of side 30 cm.

Then wire is again bend in form of rectangle of length 35 cm.

To find :-

Width of the rectangle.

Solution :-

Here, Concept is : If we are bending wire in form of square than again bending it in rectangle. Than, perimeter of square will equal to perimeter of rectangle because we are not increasing length of wire by one measure we are bending it in square and rectangular shape.

So,

Perimeter of square = 4 × side

⟶ Perimeter = 4 × 30

⟶ Perimeter = 120

Thus,

Perimeter of square is 120 cm.

According to concept, Perimeter of square and perimeter of rectangle are equal.

So, Perimeter of rectangle is 120 cm.

Let, Breadth or width or rectangle be x cm.

We know,

Perimeter of rectangle = 2(Length + Breadth)

⟶ 120 = 2×(35 + x)

⟶ 120 = 70 + 2x

\⟶ 120 - 70 = 2x

⟶ 50 = 2x

⟶ 50/2 = x

⟶ x = 25

We take, Width of rectangle be x.

Therefore,

Width of rectangle is 25 cm.

Answer 2

Answer:d) 120 mmol

Explanation:

Exit age distribution function value increases with no. of tanks added in series. So it will respond as a PFR so concentration leaving reactor will increase.
