Problem $4$: Design a Lapple standard cyclone to function as a precleaner. The particles have a density of $1250k\frac{g}{m}3,$ and have the same size distribution as in above, but the air is at $150F$ and $1$atm, and is flowing at $2000cfm.$ The cyclone need be only $65-75\%$ efficient. Specify your final choice of body diameter and the corresponding efficiency. Use $=2\mathrm{.}026**{10}^{{?}^{{?}^{?}}}-5k\frac{g}{m}-s$ and ${}_g=1\mathrm{.}043$ For Cyclone Dimensions use the note $2$ as given above.
