Suppose a blood vessel's radius is decreased to 87% of its original value by plaque deposits and the body compensates by increas
ing the pressure difference along the vessel to keep the flow rate constant.
By what factor must the pressure difference increase?
By what factor must the pressure difference increase?
1 answer:
Answer:
The pressure difference will increase by the factor of 1.75
Explanation:
For constant flow rate, coefficient of viscosity, length of the vessel and the pressure difference is inversely proportional to the fourth power of the radius of the blood vessel

Answer:
Pressure, P = 3724 Pa
Explanation:
Given that,
Depth of water,
Depth of oil,
The density of water,
The densinty of oil,
We need to find the gauge pressure at the bottom of the cylinder. So, total pressure is equal to :
So, the gauge pressure at the bottom of the cylinder is 3724 Pa.
