When you urinate, you increase pressure in your bladder to produce the flow. For an elephant, gravity does the work. An elephant urinates at a remarkable rate of 0.0060 m3 (a bit over a gallon and a half) per second. Assume that the urine exits 1.0 m below the bladder and passes through the urethra, which we can model as a tube of diameter 8.0 cm and length 1.2 m. Assume that urine has the same density as water, and that viscosity can be ignored for this flow.
1) What is the speed of the flow? It is 1.2 m/s
2) If we assume that the liquid is at rest in the bladder (a reasonable assumption) and that the pressure where the urine exits is equal to atmospheric pressure, what does Bernoulli's equation give for the pressure in the bladder? (In fact, the pressure is higher than this; other factors are at work. But you can see that no increase in bladder pressure is needed!)

During typical urination, a man releases about 400 mL of urine in about 30 seconds through the urethra, which we can model as a tube 4.0 mm in diameter and 20 long. Assume that urine has the same density as water, and that viscosity can be ignored for this flow. Part A What is the flow speed in the urethra? Part B If we assume that the fluid is released at the same height as the bladder and that the fluid is at rest...
Patient: I have blood in my urine. nurse: Do you feel pain when you urinate? patient: yes nurse: Does the urine has an extremely strong smell? Do you feel pain in your back, side, or groin? what is your temperature? Do you have a loss of appetite? Is your urine cloudy? Patient: I have pain in my back and down both legs. I couldn't tell if my urine was cloudy, I just saw blood and got upset. I'm not hungry....
A 2L bottle is filled with water and has a 2mm diameter hole in the side 2cm from the bottom and the top is open to the atmosphere. a) What is the velocity of the water stream coming out of the hole when the water is 10cm above the hole? Treat the water as an ideal fluid obeying Bernoulli's equation. Additionally, you may assume that the flow is slow enough that the velocity of the water at the top surface...
Problem 1: MSH 5-like: You are making chocolate candies and need transport the melted chocolate via a tube a short distance to the work table. You have been asked to design the tubing size (inner diameter, D), such that the flow rate does not exceed what a person can easily work (20 mL/s). The tubing needs to be 2.0 m long and can assumed to be smooth. A pinch valve will be installed, which can be used to restrict flow;...
6. The formula dS = dQ/T makes it look like a system can only increase its entropy by absorbing heat. You must however remember that this equation is only true for reversible processes. Entropy can change for a system without absorbing any heat. Consider the following scenario. You are given an insulated container with two compartments. The whole container is at the temperature T which remains constant. One compartment has a volume V1 and has n1 moles of an ideal...
