How do you calculate fluid speed?
We note that Q=V\t and the average speed is ¯v=d/t. Thus the equation becomes Q=A¯v. This is called the equation of continuity and is valid for any incompressible fluid.
How do you calculate flow rate per hour?
Use the following equations: flow rate (mL/hr) = total volume (mL) ÷ infusion time (hr) infusion time (hr) = total volume (mL) ÷ flow rate (mL/hr)
How do you calculate Bernoulli’s equation?
Since P = F/A, its units are N/m2. If we multiply these by m/m, we obtain N ⋅ m/m3 = J/m3, or energy per unit volume. Bernoulli’s equation is, in fact, just a convenient statement of conservation of energy for an incompressible fluid in the absence of friction.
How long does it take to pump gas out of hose?
Also, any gas that goes into the hose from the pump pushes gas out the end of the hose (should take about 2 ms for a pressure change at one end of an 8′ hose to be reflected on the other, if you are curious).
What is the value of P in the gas law?
P is the pressure in atmospheres (atm), V is the volume in liters (L), n is the number of moles, R is the gas constant (0.0821 L∙atm/ (mol∙K)), and T is the temperature in Kelvins (K). The gas laws describe the behavior of gases under specific conditions of temperature, pressure, and volume.
What is the relationship between pressure and temperature in gas law?
Three gas laws show the relationship between two variables when all others are held constant: Boyle’s law (pressure and volume are inversely proportional), Charles’s law (volume and temperature are directly proportional), and Gay-Lussac’s law (temperature and pressure are directly proportional).
What is the ideal gas law in chemistry?
The ideal gas law states the relationship between these properties, or variables, in a mathematical formula. The ideal gas law is PV = nRT. P is the pressure in atmospheres (atm), V is the volume in liters (L), n is the number of moles, R is the gas constant (0.0821 L∙atm/ (mol∙K)), and T is the temperature in Kelvins (K).
