Pressure drop over length of pipe Solution

Follow our step by step solution on how to calculate Pressure drop over length of pipe?

FIRST Step Consider the formula

ΔP = (32 \cdot μ \cdot V mean \cdot \frac{L p}{{D pipe}^{2}})

Next Step Substitute values of Variables

∴

ΔP = (32 \cdot 10.2P \cdot 10.1m/s \cdot \frac{0.1m}{{1.01m}^{2}})

Next Step Convert Units

∴

ΔP = (32 \cdot 1.02Pa*s \cdot 10.1m/s \cdot \frac{0.1m}{{1.01m}^{2}})

Next Step Prepare to Evaluate

∴

ΔP = (32 \cdot 1.02 \cdot 10.1 \cdot \frac{0.1}{{1.01}^{2}})

Next Step Evaluate

∴

ΔP = 32.3168316831683Pa

Next Step Convert to Output's Unit

∴

ΔP = 32.3168316831683N/m²

LAST Step Rounding Answer

∴

ΔP = 32.3168N/m²
