Fluid problems - " pipe " like questions 1. The problem statement, all variables and given/known data A fireman climbs a 8 m high ladder carrying a 5 in diameter hose that has a 1.4 in diameter nozzle. The pump has an absolute pressure of 4 atm. What is the water velocity from the nozzle? Assume that water is incompressible, its den- sity is 1000 kg/m3 , and 1 inch = 0.0254 m. The acceleration of gravity is 9.8 m/s2 and 1 atm = 1.01 × 105 Pa. 2. Relevant equations bernoulli's equation volume rate of flow 3. The attempt at a solution ok so first i found the area by converting and doing pie and all that stuff. so after i found A1 and A2, i put A2/A1 which is = to v2/v1 so that means v1 = A2/A1 * v2. with this said its time to plug into bernoulli's equation. P1 + 1/2pv1^2 = P2 + 1/2pv2^2 + pgh. P1 = given, just convert atm into Pa v1 i plugged into equation p = 1000 since its water P2 = atmopheric pressure im guessing h = 8m i plugged everything in but i got it wrong T_T i only have 3 other questions besides this one so ill post them as a reply later.
