# What is the formula to find pressure loss in fire fighting pipe lines?

The British fire and rescue services use the following formula for calculating the pressure loss due to friction in firefighting hose: Pf = 9000 f l L2 / d5 bar … where Pf is the frictional loss of pressure, in bar f is the friction factor f = 0.005 for 70 mm or 45 mm hose f = 0.007 for 90 mm hose (for 90 mm hose it is higher to allow for losses in the couplings, which are but 64 mm diameter) l is the length of the hose line, in metres L is the flow rate, in litres/minute d is the hose diameter, in millimetres The formula is approximate, and relates to internally lined hose in 25 metre lengths. You will find the formula in the old Manual of Firemanship, Book 7, Hydraulics, pumps and pump operation. David Hayward, former MIFireE

# What is heat loss formulae of water flow through PPR-C pipe line?

you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) …=Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)

# What is the formula for pipe fitting?

I believe what you are really asking is "What are the standard allowances for length?" Or in other words, how long should the threads be on the pipe? In general, the thread le…gnth is equivalent to the nominal pipe diameter. That is, if you are working with 1" pipe, you want to have 1" of thread in the fitting. In actual practice, you will cut a somewhat longer thread, so you do not run out of thread before it is tight in the fitting. If you are working with plastic glue together pipe the same theory applies. The socket on the plastic fittings is eqivalent to the nominal pipe diameter. Another possible answer you may be seeking is how to figure the length of a pipe making a 45 degree bend. That is simply the square root of 2, or 1.414 times the offset distance. For example, if you are making a 45 degree bend that needs to go 6 inches ahead, you would need a piece of pipe 8.48 inches long.

# What is a heat no on pipe?

Used for inspection. Heat numbers make it possible to trace pipe from spools fabricated on a job to material documentation from a given melt. The matching documents will tell …when and where the pipe was made, the material used and the pipe grade etc.

# What is the formula to layout pipe miters?

There is no exact formula to lay out pipe miters, but there is information that must be known to calculate the layout. This includes the diameter, wall thickness, angle, a…nd offset.

# What is the formula for weight of water in a pipe?

First, get the volume of water in the pipe. Assume the pipe is completely full, and the formula for the Volume = Volume = Pi (3.14159) X Radius of pipe 2 X Length of …pipe Then convert Volume to Weight. So, for 10 feet of 4" Inside Diameter pipe: Radius = 1/2 * Diameter = 1/2 * 4 inch = 2 inch Length = 120 inches Volume = 3.14159 X 22 X 120 = 1,508 cubic inches 1 cubic inch of water = 0.036127 pounds So: 1508 cubic inches * 0.036127 pounds per cubic inch = 54 pounds.

# What is the formula for water flow in a pipe?

- volumetric water flow - liters per second (L/s) A_*_c_/1000_=_vf">A * c /1000 = vf A = Inside area of the pipe (cm2) c = Velocity of water (cm/s) vf = Water flow… (L/s) Or - mass flow rate - kilograms per second (kg/s) m._=_ρ_*_c_*_A">m. = ρ * c * A m. = mass flow rate ρ = greek letter symbolizing density. Water's density is 1000kg/m3 Remember to put all units correctly (kg, m, s) to get kg/s. ------------------------------------------------------------------------------ U can derive by experiment........ collect water per unit time.... change flow rate of water keep time const. then divide water collected in lit by time in sec u get volumetric flowrate.. and u can find velociy of waer if u know pipe dia by e formula: Q/v = (3.14/4) * d * d Q= vol. flow rate. v= velociy d pipe dia. If pipe dia is increase or decrese use coninuttyy eq. a1v1=a2v2
