Final answer:
To determine if the flow of concrete through a hose is laminar, one must calculate the Reynolds number using viscosity, density, flow rate, and hose dimensions. Laminar flow ensures a stable and controlled application of concrete.
Step-by-step explanation:
A student has asked how to verify that the flow of concrete is laminar when it is being pumped through a hose. This involves understanding the principles of fluid dynamics, particularly the concept of Reynolds number, which determines the flow regime of a fluid through a pipe. Laminar flow is characterized by smooth, constant fluid motion, while turbulent flow involves chaotic changes in pressure and flow velocity. The properties provided, such as the viscosity of concrete and its density, are important factors for calculating the Reynolds number.
For engineering applications, such as pumping concrete, ensuring laminar flow can be critical for maintaining a stable and controlled flow rate. Appropriate calculations would need to be made using the provided measurements for flow rate, hose dimension, viscosity, and concrete density.
