Problem 6.077 Incorrect. A fireman is soaking a home that is dangerously close to a burning building. To prevent water damage to the inside of the neighboring home, he throttles down his flow rate so that it will not break windows. Assuming the typical window should be able to withstand a force up to 30 lbf, what is the largest volumetric flow rate he should allow (gal/min.), given an 10 inch diameter (D1) firehose discharging through a nozzle with 3-inch diameter (d2) outlet. The free jet from the nozzle is deflected by 90° when it hits the window as shown. Window nozzle hose Round your answer to two decimal places. Q = 11.0444 ft3/s
