Question 34
AENAT1 markNeeds review
Airplane A and Airplane B are cruising at altitudes of 2 km and 4 km, respectively. The free stream density and static pressure at altitude 2 km are 1.01 kg/m
and 79.50 kPa, respectively, and at altitude 4 km, they are 0.82 kg/m
and 61.70 kPa, respectively. The differential pressure reading from the pitot-static tubes is 3 kPa for both the airplanes. Assuming incompressible flow, the ratio of cruise speeds of Airplane A to Airplane B is _____. (round off to two decimal places)Log in to check the answer
