the 0.1" per 100 ft friction rate is the result of the life cost cycle analysis of the constant volume HVAC system. i.e. the minimum fixed and operating cost of the constant volume system over its useful life. I don't know the exact mathematical derivation to obtain the friction rate. In fact I am searching to find it.
The flow rate of water through a 2-inch pipe at 100 psi can be estimated using hydraulic calculations. Generally, a 2-inch pipe can flow around 40-50 gallons per minute (GPM) at that pressure, depending on factors like pipe length, fittings, and friction loss. For precise calculations, it's best to use the Hazen-Williams equation or consult flow tables specific to the pipe material and conditions.
0.1 inch or 0.10 inch or 0.100 inch
1 inch is equivalent to 0.0254 meters in decimals.
65/100 = 65/100.
100 microns is 3937 millionths of an inch
12 inch by 12 inch equals 1 by 1 foot 100 sq feet is having 100 of 12 by 12 inch
To calculate the exchange rate from dollars to euros, you need the current exchange rate, which indicates how many euros one dollar can buy. This rate can be obtained from financial news websites, banks, or currency converters. Once you have the exchange rate, multiply the amount in dollars by this rate to convert it to euros. For example, if the exchange rate is 0.85 euros per dollar and you have 100 dollars, you would calculate 100 x 0.85 = 85 euros.
rolling friction is 1/100 less than spliding friction
The coefficient of friction for air flow in a round duct is typically around 0.02. This coefficient may vary depending on factors such as surface roughness and airflow conditions.
The rate of a rate is 100
The rate of a rate is 100
Yes it is. The force of rollin friction is 100 to 1000 times weaker than static friction.
