WebJun 20, 2015 · Assuming the 40 psi is right across the nozzle (flow losses further back in hose won't be high, since it is large compared to opening), the velocity is sqrt (2 x pressure/density). 40 psi x 6.89476 kPa/psi = 275.8 kPa, the density of water is around 1000 kg/m³, varying slightly with temperature. sqrt (2 x 275 800 Pa/1000 kg/m³) = 23.5 m/s. WebOct 9, 2011 · The conversion factor for converting from mph to furlongs per fortnight is 2,688. So, 70 mph x 2,688 = 188,160 furlongs per fortnight. ... the pressure of the wind …

WebJun 4, 2024 · The equation of interest in this case is: P = 1014.9 – 0.361451w – 0.00259w 2 With P in mb and w in m/s. For example, a wind speed of 50 m/s (about 112 miles per hour) would be associated with a local atmospheric pressure of: 1014.9 – 0.361451 (50) – 0.00259 (2500) = 990.4 mb WebOct 4, 2002 · For flat surfaces with the wind perendicular to the surface (worst case).. F (lbs/ft^2) = 0.0046V^2 where V is the velocity of the wind in mph. For semi circular surfaces then: F (lbs/ft^2) = 0.0026V^2 where V is the velocity of the wind in mph. And V^2 is "wind velocity squared... Hope this helps. firetube WebDec 14, 2024 · To calculate the force of a 5-mile-per-hour wind, first convert the wind speed to meters per second. Using an online converter shows that 5 mph equals 2.24 m/s. Filling in the formula force equals air mass (A m) times wind speed squared: F=A_m\timesd a^2 F = Am\timesda2 gives this calculation: interstate cycle
