Friction loss in a fire hose is calculated by multiplying the friction loss coefficient by the flow rate divided by 100 to the power of two and multiplying that by the hose length divided by 100. Distance, diameter and GPM must be considered when calculating the friction loss.Know More
The formula for calculating friction loss in a fire hose is C * (Q/100)^2 * L/100. C is the friction loss coefficient, Q is flow rate in gallons per minute and L is the length of the hose. The friction loss coefficient is determined by the diameter of the hose. The formula can be solved by hand, with a scientific calculator or by utilizing various friction loss calculators available on the Internet.
There are important points to remember when calculating friction loss in a fire hose. Friction loss varies with weave, quality, lining, type and age of the hose. It is nearly independent of pressure and increases as flow increases. The greater the length of the hose, the higher the friction loss is. Each doubling of water flow increases friction loss four times.
Friction develops between the inside surface of the hose and the water moving through it. The pounds per square inch are reduced at the other end of the hose because of this turbulence.Learn more about Arithmetic
The compound annual growth rate, or CAGR, of an investment is calculated by dividing the ending value by the beginning value, taking the quotient to the power of one over the number of years the investment was held and subtracting the entire number by one. Then, turn the answer into a percentage from decimal form. The CAGR allows you to see an investment without all the ups and downs as if it had grown at an even, steady pace over the years.Full Answer >
A coupon rate is calculated by using the formula c(1 + r)^-1 + c(1 + r)^-2 + ... + c(1 - r)^-y + B(1 + r)^-y = P. In this equation, the variable of c represents an annual coupon payment that is calculated in dollars, and not a percentage. The variable Y equals the number of years to maturity, the variable B stands for the par value and the variable of P represents the purchase price.Full Answer >
