Question

The actual lab you will do involves measuring stream discharge. Let's look at some units. 7. If our unit of distance is "length", and our unit of time is "time", what would be the unit of velocity? 8. What would be the unit of stream width? 9. What would be the unit of stream depth? 10. What would be the units of stream width multiplied by stream depth? (hint: this is called the cross- sectional area of a stream). 11. Finally, what would be the units of cross-sectional area multiplied by velocity? he book says that at the peak of the 1993 Mississippi River flood, the discharge at St. Louis Missouri was 1,070,000 cubic feet per second (ft' s). If there are 7.48 gal was this discharge in gallons per day? (please show your work) lons in one cubic foot, what

Explanation / Answer

7. As per the question unit of distance is length while the unit of time is time.

The formula for velocity is length/time

Therefore the unit of velocity would be = unit of distance/ unit of time = length/time

8. The width of any object or entity is expressed in the form of distance and in the question given the unit of distance is length, therefore the unit of width of stream would be length.

9.  The depth of any object or entity is again expressed in the form of distance and in the question given the unit of distance is length, therefore the unit of depth of stream would be length.

10. As in the question above the units of width of stream and depth of stream are length and length respectively, therefore the unit of stream's width multipied by stream's depth would be length2.

As per Chegg's policy we are adviced to attempt only the first four parts of a questioner, please post the remaining questions as a different questioner. Thanks
