A proton enters near the positive armature of a capacitor perpendicular to the lines of the electric field with a speed of 3.0 · 10 ° m / s. If the intensity of the electric field is 1.4 10 * V / m, the distance between the armatures is 1.2 mm and the length of the capacitor 3.5 cm, determines the flight time inside the condenser and the output speed of the proton.

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 18oc and exits at 6.0 bar. the refrigerant undergoes a throttling process. determine the temperature, in oc, and the quality of the refrigerant at the exit of the expansion valve.

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
