Mass flow

Mass flow, also known as mass transfer and bulk flow, is the movement of material matter. In physics, mass flow occurs in open systems and is often measured as occurring when moving across a certain boundary characterized by its cross-sectional area and a flow rate. In engineering and biology it may also be a flow of fluids in a tube or vessel of a certain diameter.

Examples include, blood circulation, transport of water that assimilates in xylem vessels and phloem tubes of plants. This relies upon the cohesion of water molecules to each other and adhesion to the vessel's wall by hydrogen bonding. If an air bubble occurs the flow will be stopped as the column is broken and the pressure difference in the vessel cannot be transmitted; this is called an air lock.

Question:I need to make a flow chart .. mouth to anus 3 parts of the small intestine included,, How would i do that?... Just list parts?

Answers:Input: Food --> Mouth --> Stomach --> is the food essential to the body?---No---> Anus +++++++++++++++++++++++++++++++|_______Yes-->extract nutrients and give them to the blood.

Question:1. create a flow chart that will ask the user for two numbers (x, x) it will display the GCF of the two numbers 2. create a flow chart that will ask the user for the two number (x, y) it will display the LCM of the two numbers 3. create a flow chart that will ask the user for a number print ''prime'' if prime else print ''not prime'' plssssssssssssssssssss help thank u

Answers:Since its very time consuming to draw a flowchart I will give you the rough algorithm of how solve these problems 1. GCF Enter a and b while(a!=b) if(a>b) Then a=a-b else b=b-a gcf=a (If you don't understand this then put some numbers for a and b and work out according to the steps. Then you will understand the logic) 2. for lcm calculate gcf as shown above and then lcm=a*b/gcf 3. Sorry. I'm not able to come up with a logic to differentiate between prime and non prime. However, it is possible to find all prime numbers within a given range of numbers (like 50 to 150) but the flowchart for that is very complex

Question:I posted one of these early in the week, and quite frankly, it was flawed. Very flawed. I took into account all of the feedback I received, and overhauled it. Take into account that the dates are not by any means 100% correct, but they are ballpark-range, and are close enough for my purposes. Is this at all accurate. If not, please say so, and what needs to be fixed. I know that the inter-relations of music can never be completely mapped out using a flow chart, but this is what I need to do: http://yfrog.com/1qevolutionofmusic2p Sorry, the link seemed to not want to register. It is there now.

Answers:it seems accurate to me

Question:The speed S of blood that is r centimeters from the centre of an artery is: S=C(R^2-r^2) where C is a constant, R= radius of artery, and S is measured in centimeters/second. Suppose a drug is administered and the artery begins to dialate at a rate of dR/dt. At a constant distance r, find the rate at which S changes with respect to t for C=1.76x10^5, R=1.2x10^-2, and dR/dt= 10^-5. The answer is .04224. I just need help getting there. thank you! :)

Answers:this question has already been answered! dS/dt = C[ 2R*dR/dt] =1.76*10^5[2*1.2*10^-2*10^-5] = 0.04224 round to 0.042 note since r is a constant its derivative is zero.
