Subsonic non afterburning engine has takeoff thrust of 8000 Newton and is operating with BPR of 1.2 then, what will be the approximate value of thrust at cruise.

Subsonic non afterburning engine has takeoff thrust of 8000 Newton and is operating with BPR of 1.2 then, what will be the approximate value of thrust at cruise. Correct Answer 2001.5 unit

Given, Thrust T1 = 8000N, BPR = 1.2 Now, thrust at cruise T = 0.60 * T10.9 * e (0.02*BPR) = 0.60 * (8000)0.9 * e (0.02*1.2) = 0.60*3256.724*1.024 = 2001.49 = 2001.5 unit.

Newton, Einstein, and Tesla working alone can do a piece of work in 20, 30, and 60 days respectively. All three of them start the work together, but after x days Newton leaves and then after y more days Einstein leaves and Tesla completes the remaining work. If Einstein had not left, Tesla and Einstein would have completed the remaining work in (y + 6) days after Newton had left. If both Newton and Einstein had stayed, the work would have been completed in (x + 6) days. What is the total number of days taken to complete the work?
