## Which of the following on which rate of flow of liquid does not depend?

The rate of flow of liquid through an orifice at the bottom of a tank does not depend on. And it is independent of the density of the liquid.

**What are the dimensions of rate of flow of liquid?**

What is the dimensional formula of rate of flow of liquid? The volume of the liquid flowing through pipe per second is the rate of flow of liquid. So, dimensional formula is [M0L3T–1].

**What are the dimensions of pressure?**

Or, P = [M1 L1 T-2] × [L2]-1 = M1 L-1 T -2. Therefore, the pressure is dimensionally represented as M1 L-1 T -2.

### What is liquid viscosity?

Viscosity is a measure of a fluid’s resistance to flow. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.

**When liquid is flowing through a pipe the velocity of the central layer is?**

Hence velocity of the fluid flow is minimum or zero at surface and maximum at the center in pipe flow.

**What is the unit of volume flow rate?**

meters cubed per second

In S.I. units (International System of Units), volume flow rate has units of meters cubed per second, m 3 s \dfrac{\text m^3}{\text s} sm3start fraction, start text, m, end text, cubed, divided by, start text, s, end text, end fraction, since it tells you the number of cubic meters of fluid that flow per second.

#### How can we write energy using the MLT system?

Explanation: Energy or work can be written dimensionally by [M][L]2[T]2. This is by adopting the basic SI or MKS units. Where, [M] is the mass, [L] is the length and [T] is the time. Thus, the correct option is [M][L]2[T]2.

**What is MLT physics?**

The equations indicate how force depends on mass, length and time. We use the symbols MLT (not in italics) to indicate the fundamental dimensions of mass, length and time.

**What is fluidity of a liquid?**

The ability of a substance to flow is called fluidity. The substances which show fluidity are called fluids. Liquid and gas are examples of fluids. The particles of liquid and gas are able to move freely because there is a large space between them.

## How are viscosity and flow rate related?

The short answer is; as viscosity increases, flow rates decrease.

**When a liquid is flowing through a pipe the velocity of the liquid is with no slip condition *?**

The fluid velocity in a pipe changes from zero at the surface because of the no-slip condition to a maximum at the pipe center.

**How do you calculate flow rate in a pipe?**

How to calculate volume flow rate in a pipe? You multiply the speed of the liquid flowing through the pipe by the pipe’s cross-sectional area.

### How do you find the volume per second of water?

Measure the number of liters or gallons in the container, and divide that number by 15. This gives the flow rate in liters per second or gallons per second. The formula is F = V/T, where F is the flow rate, V is the volume and T is the time.

**What is formula of liquid volume?**

The volume of a portion of the fluid in a pipe can be written as V = A d V=Ad V=AdV, equals, A, d, where A is the cross sectional area of the fluid and d is the width of that portion of fluid, see the diagram below.

**How do you find volume flow rate?**

You can calculate the volumetric flow rate by using the equation shown below:

- volumetric Flow Rate (Q) = Flow Velocity (V) × Cross-sectional Area (A)
- Mass Flow Rate (ṁ) = V × A × ρ

#### What is the unit of water flow?

Flow is the volume of fluid that passes in a unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), or other various units.

**What are the various methods of dimensional analysis to obtain a functional relationship between various parameters influencing a physical phenomenon?**

An elementary method for finding a functional relationship with respect to a parameter in interest is the Rayleigh Method, and will be illustrated with an example, using the MLT system. This means that D = f(l,ρ,μV,g) where f is some function.

**In what way does dimensional analysis help in presenting experimental data?**

Dimensional analysis helps in determining a systematic arrangement of the variables in the physical relationship, combining dimensional variables to form non-dimensional parameters. It is based on the principle of dimensional homogeneity and uses the dimensions of relevant ariables affecting the phenomenon.

## What is dimensional analysis class 11?

Dimensional analysis is the practice of checking relations between physical quantities by identifying the dimensions of the physical quantities. These dimensions are independent of the numerical multiples and constants and all the quantities in the world can be expressed as a function of the fundamental dimensions.
