Ethylene propylene rubber (EPR, sometimes called EPM referring to an ASTM standard) is a type of synthetic elastomer that is closely related to EPDM rubber.Since introduction in the 1960s, annual production has increased to 870,000 metric tons. Properties EPM is considered a valuable elastomer due to its useful chemical and physical properties; it is resistant to heat, oxidation, ozone and the

Your pressure losses will be dominated by the rubber hose and high friction fittings such as the nipples and flow through the branch of any tees, sharp elbows etc. Bear in mind that the friction losses for the same flowrate are in the order of Di1/Di2 ^5. Hence

into heat, causing a pressure loss. For example, changing from a 5/8 hose to a 1/2 hose will more than double the pressure drop. For hydraulic systems, rules of thu for fluidvelocity have been developed that provide upper limits of acceptable friction and heat build-up. For industrial hoses

Rubber wire-braided, REELTEX®, and HOTSTOP hose provide hardline hose performance characteristics that are appropriate for wildland firefighting. Due to the low burst pressure and low abrasion resistance, 1-in cotton-synthetic is not recommended as a hardline hose.

As water passes through a hose, friction between the water and the inside surface of the hose causes turbulence, which slows the water. The results in a PSI drop (pressure loss) at the other end of the hose. The higher the gpm passing through a hose, the more turbulance and friction loss will result.

Pressure loss for 100'' of hose is 20 psi, therefore, the loss in 150'' of hose is: 150''/100'' x 20 psi = 30 psi. As a rule of thu, loss for each set of couplings equals 5% of the loss per 100'' of hose. Therefore, pressure loss = .05 x 20 psi = 1 psi per set of couplings.

Note that by undertaking the pressure loss test on several hoses of different length, it will be possible to extrapolate results to any length of hose and also to estimate the pressure loss of the end fittings. 4.4 MINIMUM BEND RADIUS When bent to the minimum

Determining of pressure loss On the vertical scale find the flow quantity in litres/minute. From this point go horizontally to the right until the oblique line of the hose bore is crossed.

Keep in mind that if you transfer gaseous substance through the hose then you need to find the ratio of the density of gas over the density of water and adjust the pressure drop respectively. For example if you transfer natural gas (density = 0.050 lb/ft 3) and knowing that water density = 62.4 lb/ft 3 we can find out the pressure drop as the following: 3.7 x (0.050/62.4) = 0.0030 psi/ft or 0
