2. Ensure use for services containing solids with specific gravity twice or more than that of process fluid. 3. Efficiency of a cyclone separator is proportional to the diameter. A larger cyclone diameter leads to less efficient separation, a smaller cyclone diameter provides more efficient separation.
The spot and forward rates are each used in currency exchanges. The spot rate refers to the rate for a currency exchange that is settled and delivered immediately.
