A sodium hypochlorite tank's full working capacity
is 23,000 gallons. Its current level is at 1,200
If a 38-tooth gear running at 360 rpm is driving gallons. How many gallons does the delivery
another gear at 144 rpm, what is the number of driver need to add to bring it to 70% capacity? -
teeth on the driven gear? - ANSWER - ANSWER -Solution:
Solution: driver Gear x Driver RPM=Driven Gear 23,000 gallons max capacity x 70% desired
x Driven RPM capacity = 16,100 gallons desired.
38 x 360 = N x 144 16,100 gallons desired - 1,200 gallons current
13,680 = 144N level
13, = 144N / 144 14,900 gallons needed to add
95 = N
(95 Tooth Gear
