- The force of the atmosphere at sea level against the outside of a 10 m2m2 store window is about 1 million NN. Why doesn't this shatter the window? Why might the window shatter in a strong wind blowing past?You irrigated 55 acres of soybeans. You used an 8-inch pipeline with a water velocity of 5 feet per second. You applied 1 acre-inch of wa- ter. (Note: 1 acre-inch is 27,154 gallons per acre and 231 cubic inches equals 1 gallon.) a. What is the flow rate? b. How many gallons did it take to irrigate the 55 acres?10.) Please help with equation, gravity is g=32.2 ft/sec^2 or g=9.81 m/sec^2
