Collars A and B start from rest, and collar A moves upward with an acceleration of 3t2 mm/s2. Know that collar B moves downward with a constant acceleration and that its velocity is 150 mm/s after moving 700 mm. Determine the distance through which block C will have moved after 3 s. The distance through which block C will have moved after 3 s is mm.

Apreheater involves the use of condensing steam at 100°c on the inside of a bank of tubes to heat air that enters at 1 atm and 25°c. the air moves at 5 m/s in cross flow over the tubes. each tube is 1 m long and has an outside diameter of 10 mm. what is the minimum value of nl needed to achieve an outlet temperature of t 75 c? what is the corresponding pressure drop across the tube bank?
