Consider a wing mounted in the test-section of a subsonic wind tunnel. The velocity of the airflow is 160 ft/s, and the velocity at a point on the wing is 293 ft/s.
If the test-section air temperature is 510°R and the flow velocity is increased to 450 ft/s, what is the pressure coefficient at the same point?

(Round the final answer to three decimal places.)

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
