A high-specific-thrust/low-bypass-ratio turbofan normally has a multi-stage fan behind inlet guide vanes, developing a relatively high pressure ratio and, thus, yielding a high (mixed or cold) exhaust velocity. The core airflow needs to be large enough to ensure there is sufficient core power to drive the fan. A smaller core flow/higher bypass ratio cycle can be achieved by raising the inlet tempe… WebWhat is the formula for Power? Power = Force x Distance / Time or P = F x D / t. meaning P = Power in ft. pounds per minute, D = distance in feet and t = time in minutes. What is the formula for Horsepower? Horsepower = Power (in ft. lbs./min.) divided by 33,000 or HP = Power/33,000. What is the formula for Velocity?
