How much heat is absorbed by 100g of ice at -10⁰C to become water at 20⁰C? • Specific heat: Water (Ice) = 2,090 J/Kg•⁰C, Water (Liquid) = 4,186 J/Kg•⁰C • Latent heat of fusion (Water) = 3.33 x10^5 J/Kg J/Joules

The speed of flow in the second pipe is 0.49 m/s

Explanation:

In our case, this problem shows a Fluid flow. We are to solve the speed flow of fluid to the second pipe.

For the formula, we will be using the Continuity equation for Fluid flow.

where

is the area of the first pipe

is the speed of fluid flowing in the first pipe

is the area of the second pipe

is the speed of fluid flowing in the second pipe

For the given information

this is the radius of the first pipe

or (pascal)

Solving the problem

Here, we focus only to solve for the speed flow of fluid in the second pipe, so we will not be needing the other information stated in the problem.

Use the continuity equation,  substitute the given information.

Deriving the equation, we have:

Take note that the area for the inlet of a pipe is a circle, therefore the area of a circle is,

Substitute the area of circle in the derived formula for continuity equation, we have:

Therefore, the speed flow on the second pipe is 0.49 m/s which means that the speed flow on the second pipe slows down.

Hello!

Using a diagram, illustrate the relationship between:

1.) mass (m) and acceleration (a) if the same force acts on objects of different masses​

According to Newton's second law, we understand that the resulting force acting on a body is directly proportional to the mass product by the acceleration it acquires.

For a body of different mass , with the same force (F), we will have different acceleration .
