When your urinary bladder is full, the bladder pressure can reach up to 60 mm H20. What is this pressure in units of Pascal? Assuming that there is no height difference between your urinary bladder and where your urine comes out, calculate the speed at which your urine comes out. The density of urine is 1030 kg/m³. If the diameter of a urethra is 6 mm, estimate the volume flow rate of urine as it comes out in units of liters per second. d. a. b. C. If a full bladder constitutes 500 mL of urine, how long will it take you to remove all of the urine from your bladder? The answer in part (d) is somewhat a realistic time for peeing? What should we factor in in order to make it more realistic? е.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
