The fish has a body mass of {eq}\rm 0.2\ kg {/eq}. Calculate the volume of water it will need to pass over its gills each hour to supply the oxygen required when resting. Fish: Fish are gill-bearing animals tha...
If you watch the surface of a frozen pond slowly melt on an atypically warm winter afternoon, and watch the same thing occur on the surface of a nearby good-sized frozen puddle, you might observe the ice in each appear to be transformed to water at about the same rate. But what if al...
Calculate the volume of one foot of 1-inch Schedule 40 steel pipe. Published data shows that the internal diameter is 1.05-inches. Using the volume formula for cylinders, V= (diameter/2)^2 X pi X length X 7.48 gallons/cubic foot. Substituting terms V = (1.05/2) ^squared X 3.1416 X ...
Spillages have accumulated in the sump over the many years of use although the waste volume or evaporation rates are not known. Access to the sump is via a 15 cm diameter drain from a sloped floor. The sump is buried in the ground beneath the floor. Previous experience showed that ...
