According to the operating procedures for the equipment, it states that when the oil tank is at a low liquid level, the flow rate of oil entering the tank should not exceed 1 m/s. How can the flow rate of oil entering the tank be controlled? Is it to control the flow rate of the oil? How can we determine that the flow rate of the oil entering the tank is less than 1 m/s? For example, if the pipeline for feeding oil into the tank has a diameter of DN100, what flow rate needs to be controlled? Thanks, those who know please share
To control the flow rate of oil entering the tank, it is necessary to control the oil flow volume. The flow rate can be controlled by adjusting the flow control valve on the flow meter, to ensure that the flow velocity does not exceed the specified value. Flow rate refers to the volume of fluid that passes through a cross-section per unit of time. To know the flow rate of oil entering the tank, a flow meter can be used for monitoring. Taking a DN100 pipeline as an example, the inner diameter of DN100 is approximately 100 mm, that is, 0.1 m. If the flow velocity is no more than 1 m/s, then using the formula for the cross-sectional area of a circular tube, A=πd²/4, the cross-sectional area A is approximately 0.00785 square meters. Therefore, the flow rate Q (volumetric flow rate) = flow velocity V (1 m/s) × cross-sectional area A, which is approximately 0.00785 cubic meters per second, or 7.85 liters per second. Therefore, it is necessary to keep the flow rate of the oil at less than 7.85 liters per second. .
