Webinvolves the calculation of the mass flow rate and the evolution of the refrigerant properties all along the tube. For a given capillary tube geometry (inner diameter and length) and given operative conditions, the whole problem becomes fully implicit in the mass flow rate and in the outlet refrigerant properties. Therefore, the mass flow is Webi.e., the flow of mass m through a surface per unit time t.. The overdot on the m is Newton's notation for a time derivative.Since mass is a scalar quantity, the mass flow rate (the time derivative of mass) is also a scalar quantity. The change in mass is the amount that flows after crossing the boundary for some time duration, not the initial amount of mass at the … WebThe refrigerant mass flow rate is measured coriolis flowmeter which is installed between the indoor and outdoor unit.
