Physics equations Flashcards
What is the equation for the pressure exerted by a column of fluid?
Pgh (density)
Give the equations for pressure, force, momentum and density?
Pressure = force/area
Force = mass x area
Momentum = mass x velocity
Density = mass / volume
What are the three equations for work?
Force x distance
Pressure x volume
Mass x shc x temp change
What are the two equations for power in a circuit and 1 for power in the heart?
Voltage x current (VI) and I squared x resistance
Heart = pressure x volume
What are the different equations for energy?
Energy?
Kinetic?
Potential?
Electrical?
Energy = power x time
Kinetic = 1/2mv2
Potential = mgh
Electrical (J) = VIT
How do we calculate relative humidity?
Actual pressure divided by SVP x 100
What is the ohms law equation?
Voltage = current x resistance
What is the equation for charge?
Capacitance?
Defib capacitance?
Amps x seconds
Charge x volts
1/2cv2
What is the equation for resistance in a vessel?
Resistance = pressure / flow
What is the bernoulli equation?
1/2 pv2 + p
Density
Potential energy
What is Reynolds equation?
Vpd/n
