# What is the force of the water flowing vertically onto a paddle from a 20-mm diameter pipe and a flow rate of one liter per second and does the force double if the flow rate is doubled?

Would you like to merge this question into it?

#### already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

#### exists and is an alternate of .

You need to know the distance from the pipe to the paddle to ascertain the velocity. Force = mass of water x square of the velocity assuming it is stopping at the paddle. The force would quadruple if it were following twice as fast since the force is proportional to the velocity squared.

# What is the difference between a single check valve and a double one and can you fit one in the hot water pipe to a shower to prevent cross flow.?

 Answer   A double check valve is merely two single check valves in close series.   This means that under negative pressure the water that momentarily bypasses  

# 'What is the constant force Nm of water flowing through a 20 mm pipe at 1 liter per second and does the force double if the flow is doubled'?

IT means that you arestupid

# One inch diameter pipe with sixty PSI reading you would like to know what your water flow rate will be?

  Well this is a very poor question as one would have to know the kind of piping material as there is friction losses to consider (Hazen Williams formula and Boyle's law)

# What is the water flow rate in a 24 inch diameter pipe in gallons per minute when the flow velocity is 3 feet per second?

what is the discharge flow of 10m/s passing from 2ft pipe

# What is optimum flow rate for laminar flow in water pipe?

Less then 8 FPS (depending on the material ) See   Hazen - Williams

# How do you determine flow rate by pipe size?

  By knowing the availabe pressure and the diameter / material of the piping

PSI /diameter /

# How do you calculate flow rate in a pipe?

Q = V*A Q is flow rate V is fluid velocity A is x-sectional Area

# How do you calculate pipe diameter given flow rate and pressure?

The simplest way to calculate the pipe diameter would be using flow rate & velocity in the formula, diameter=root((4*Flow)/(Pi*Velocity)).  In order to find the velocity from

# Do the length of pipe effect the flow rate of water?

Stepping down the size of the pipe into a smaller one in fact WILL  NOT GIVE MORE PRESSURE! The smaller the size of the pipe, the less  water it can carry, and ultimatley di

# How can you calculate water velocity from flow rate or diameter of pipe?

Flow Rate Q= VA or V=Q/A. where q=flow rate, V= velocity, A=area.

# What is the flow rate of water through a 20 inch pipe at 2500 psi?

For laminar flow? For a full pipe? for a 3/4-full pipe? For a 1/2-full pipe? It all makes quite a difference. Please repost your question with a little more information. It wo

# Is the flow of water flowing at 2 meter per second through 3 inch diameter GI pipe laminar or turbulant?

Calculate the Reynold's number. As a rule of thumb, any Reynold's number < 2000 is considered laminar, 2000

# What is the rate of water flow through a 100mm diameter pipe with 300mm head pressure?

300mm is a very low head, you can't expect much flow through that  pipe, but you can work it out from the mechanical energy balance  equation.

# What is flow rate for copper pipe?

This question is literally impossible to answer correctly because there is no given size or pressure of the liquid or gas travelling through it.
