The main issue is body composition (see the body fat calculator for more). Calorie expenditure will vary depending on the ratio of body fat to muscle or lean mass. NOTE that as our bodies adapt to exercise and our body composition changes - so will the amount of Calories burned.
The definition of a throttle is a valve that controls the fluid flow. An example of a throttle is a car part that controls how fuel moves through the system. Throttle is defined as to control the speed of an engine or the flow of fuel in an engine, or to hold down or choke.
The drum attached to the throttle then provides the space for the vapor and liquid to separate from each other, where the liquid travels downward and the vapor upward. (The drum is not attached to the throttle. The throttle valve is piped to a nozzle â which is welded to the flash drum. The flash drum is sized according to the Brown-Souders equation and is designed to facilitate the separation of the 2-phase mixture resulting from the adiabatic â isenthalpic expansion of the feed fluid through the throttle valve.)
