For a given surface with known wetting behavior, the ratio of the height to the diameter of an inkjetted drop is known to be about 1:10 (the diameter of a drop is 10 times the height). The density of the liquid is 1000 kg/m^3. Now, you have tuned your inkjet to produce 50 picoliters drops of this liquid, and jet them on the same surface.

a. What is the average height of these inkjetted drops, if you assume the drops are spherical caps?
b. If the maximum allowable variation in volume is 10% of the average volume, what should the maximum allowable variation in height be?
