Some aeronautical engineers are designing an airplane and wish to predict the lift produced by their new wing design. the chord length lc of the wing is 1.12 m, and its planform area a (area viewed from the top when the wing is at zero angle of attack) is 10.7 m2. the prototype is to fly at v

Distinguish between a transverse wave and a longitudinal wave.

What equation is used to calculate the weight of an object on a plant ?

8.29 two streams containing pyridine and acetic acid at 25°c are mixed and fed into a heat exchanger. due to the heat-of-mixing effect, it is desired to reduce the temperature after mixing to 25°c using a stream of chilled ethylene glycol as indicated in the diagram. calculate the mass flow rate of ethylene glycol needed. the heat capacity of ethylene glycol at these conditions is approximately 2.8 kj/(kg k), and the enthalpy change of mixing (δmixh) is given below.
