Answer:
8 hours
Step-by-step explanation:
basic equation
Q (flow rate) = V (volume)/ t (time)
so to find the time we just rearrange the equation and become
t = V/Q
V of cylinder
V = πr²T
and r (radius) = ½ diameter
V = 3.14 x 5² x 1.4
V = 109.9 m³
if the Q is 13 m³/hour then
t = 109.9/13 = 8.453 hours
round to nearest hour = 8 hours
The greatest outputs will be by function h.
Hope this helps.
This is the way we are going to solve it.
1h = 60m ----------Steps
1. 7/8w=(1+1/6)h
2. 7/8w=(6/6+1/6)h
3. 7/8w=7/6*60m
4. 7/8w=(7*6*10*m)/6
5. 7/8w=70m
6. m=(7/8w)/70
<span>7. m=1/80w
