Recall this equation for a device in a direct current circuit:
P = IV
P is the power dissipated by the device, I is the current through the device, and V is the voltage drop of the device.

If we choose to use the ampere as the unit of current and the volt as the unit of voltage, then the product of the current and the voltage will give the power with watts as the unit.

Answer:

P_1 - P_2 =219.62\ Pa

Explanation:

given,

density of blood = 1060 kg/m³

v₂ = 0.800 m/s

v₁ = 0.475 m/s

change in pressure calculation

using Bernoulli's equation

P_1 +\dfrac{1}{2}\rho v_1^2 = P_2 + \dfrac{1}{2}\rho v_2^2

both are at same level

P_1 - P_2 =\dfrac{1}{2}\rho (v_2^2- v_1^2)

P_1 - P_2 =\dfrac{1}{2}1060\times (0.8^2- 0.475^2)

P_1 - P_2 =219.62\ Pa

the change in pressure is equal to 219.62 Pa
