It is stated that as volumetric flow rate increses the available head decreases. Can anybody explain this sentence?
The flow rate and available head relation is a concept in fluid mechanics that describes the relationship between the flow rate of a fluid and the available head, or the potential energy, of the fluid. It is an important factor in understanding the behavior of fluids in pipes, channels, and other systems.
The flow rate and available head relation can be calculated using the Bernoulli's equation, which states that the sum of the pressure, kinetic energy, and potential energy of a fluid remains constant along a streamline. This equation can be rearranged to solve for the flow rate and available head at a given point in a fluid system.
The flow rate and available head relation is crucial in determining the performance of a pump. The pump needs to provide enough head to overcome the frictional losses in the system and maintain the desired flow rate. If the available head is too low, the flow rate will decrease, and if the available head is too high, it can cause damage to the pump and system.
The flow rate and available head relation can be affected by various factors such as the diameter and length of the pipe, the fluid's viscosity, and the pump's efficiency. Changes in these factors can alter the available head and, consequently, the flow rate of the fluid.
The flow rate and available head relation can be optimized by selecting the appropriate pump for the fluid system, ensuring proper maintenance of the system and pump, and minimizing any losses due to friction or other factors. Additionally, using a pump with variable speed control can help adjust the flow rate and available head to meet the system's needs.
