What does Δp = QR mean in words?
Pushing a viscous fluid through a pipe requires a drop in pressure along the direction in which the fluid is flowing through the pipe.
If there is no pressure difference across a pipe, the flow is 1/R.
If you increase the flow of a viscous fluid, you increase the pressure at the end of the pipe toward which the fluid if flowing.
A viscous fluid will always move more and more quickly through a pipe because the pressure increases in the direction in which the fluid is flowing through the pipe.
Viscous fluid will only flow through a pipe if the resistance is zero.
Homework Answers
Δp = QR
when there is no change in pressure, we have Δp constant, hence
Q 
1/R
If there is no pressure difference across a pipe, the flow is 1/R.

In hemodynamics, blood flow through the cardiovascular system
can be modeled as an electric circuit in which the blood serves as
electricity, the blood vessels as resistive wires, and the heart as
a battery (see Figure 1).

Ohm’s law states that the voltage drop ΔV across each element,
the current I flowing through it, and its electrical
resistance R are related by ΔV = IR. In a blood vessel, pressure

just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
