Question 1
A cylindrical pipe of diameter 0.1 m carries water (μ = 0.001 Pa.s). If the pressure drop over a length of 5 m is 5000 Pa, calculate the flow rate using Poiseuille's law.
💡 Hint: Remember to substitute the values correctly and calculate π accurately.
Question 2
Determine the Reynolds number for water flowing through a 0.1 m diameter pipe at a velocity of 2 m/s. Assume the density of water is 1000 kg/m³.
💡 Hint: Use the Reynolds number formula and remember the properties of water at room temperature.
