Homework Answers
Flow rate is defined as volumetric rate of fluid flow through a certain area in unit time, where as flow speed is just a speed of streamlines.
Hence difference between flow rate and flow speeds is that flow rate indicates a volumetric flow rate of change of fluid flow.

A difference between spermatogenesis and oohenesis is
Question 11 1 pts A difference between spermatogenesis and oogenesis is each primary spermatocyte produces 4 gametes while each primary oocyte produces one gamete. O spermatogenesis uses the process of meiosis and oogenesis uses the process of mitosis. O oogenesis is completed prior to fertilization and spermatogenesis is completed after fertilization. oogenesis continues from puberty until death while spermatogenesis occurs from birth until death.

Question 29 3 pts The biggest difference between chlorophyte life cycles and the generalized life cycle of land plants is that chlorophytes are unable to reproduce sexually; their only method of reproduction is asexual. O land plants alternate between a diploid and a haploid stage; chlorophytes are always haploid. O land plants undergo mitotic cell divisions as part of their life cycle; chlorophytes divide through binary fission. O chlorophytes require an endosymbiotic host in order to complete their life cycle....

Problem 1. (29 pts) Jar testing for the water treatment system with a design flow of 37,843 m/d indicates a ferric chloride dosage of 50 mg/L is optimal. The raw water suspended solids concentration is 35 mg/L and the alkalinity is 65 mg/L as Cacos. Pilot studies indicate that the sludge from the settling tanks will consist of 1.5% solids and have a wet sludge specific gravity of 1.15. (a) Determine if it is necessary to adjust the alkalinity of...

1. What is the flow rate if the average headway between 100 vehicles is 5 seconds? 2. What is the difference between time-mean speed and space-mean speed? 3. How would you observe the speed, flow, and density of a roadway? Using Greenshields, what is the speed of traffic if the free flow speed is 70 miles per hour, the current density is 70 vehicles per mile, and the jam density is 70 vehicles per mile? 4. What is the speed...

What is the difference between the cash flow approach and the opportunity cost approach for replacement decisions? The opportunity cost approach factors in the trade-in allowance, whereas the cash flow approach does not. These are actually two names for the exact same approach. Thus, there is absolutely no difference between them. Only the cash flow approach factors in taxes, so it is the only one we should ever use. The opportunity cost approach treats the sale proceeds from selling the...

Question 4 1 pts A jet develops a 0.79 V potential difference between the tips of its wings when flying above a region of the earth where the earth's magnetic field points essentially vertically upward and has a strength of about 35 HT (106 T). If the jet's wingspan is 35 m, what is its speed? Give your answer in km/s.
