Adiesel engine accomplishes ignition without a spark plug by an adiabatic compression of air to a temperature above the ignition temperature of the diesel fuel, which is injected into the cylinderat the peak of the compression. suppose air is taken into the cylinder at 280 k and volume v1and is compressed adiabatically to 560 0cand volume v2. assuming that the air behaves as a n ideal gas whose ratio of cpto cvis 1.4, calculate the compression ratio v1/v2of the engine.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
