Calculate head loss per meter clarification

In summary, head loss per meter clarification is a measure of pressure drop in a fluid as it flows through a pipe or channel. It is important in fluid mechanics for designing and optimizing systems. It is calculated using the Darcy-Weisbach equation and is affected by factors such as fluid velocity, pipe diameter, and roughness. To minimize head loss, the fluid velocity can be reduced, larger pipe diameters can be used, and obstructions should be avoided.

Calculate the head loss per metre length of a capillary tube which has a bore radius of 0.45 mm when a fluid of density 850 kg/m3 and viscosity of 25 cP is flowing at a rate of 50 l/hr. State whether the flow is turbulent or laminar.

I have attached my attempt at a solution using poiseuille's law any feedback /clarification is greatly appreciated

1. What is head loss per meter clarification?

Head loss per meter clarification is a measure of the pressure drop that occurs in a fluid as it flows through a pipe or channel. It is typically expressed in meters of fluid per meter of pipe or channel length.

2. Why is it important to calculate head loss per meter clarification?

Calculating head loss per meter clarification is important in fluid mechanics, as it helps engineers and scientists understand and predict the behavior of fluids in a system. This information is crucial in designing and optimizing fluid systems for various applications.

3. How is head loss per meter clarification calculated?

Head loss per meter clarification is calculated using the Darcy-Weisbach equation: hL = f * (L/D) * (V^2/2g), where hL is the head loss per unit length, f is the Darcy friction factor, L is the pipe length, D is the pipe diameter, V is the fluid velocity, and g is the acceleration due to gravity.

4. What factors affect head loss per meter clarification?

Head loss per meter clarification is affected by several factors, including the fluid velocity, pipe diameter, pipe length, and fluid properties such as viscosity and density. Roughness of the pipe surface and the presence of fittings or obstructions can also impact head loss.

5. How can head loss per meter clarification be minimized?

Head loss per meter clarification can be minimized by reducing the fluid velocity, using larger pipe diameters, and keeping the pipe length as short as possible. Additionally, using smooth pipe materials and avoiding obstructions or fittings can also help reduce head loss.
