Subject: Venturi tubes gen. Помогите, пожалуйста. во 2 предложении мне кажется, дожно быть -When fluid flows through? или тут правильно? спасибо.
Venturi tubes, also termed "Venturis", are used to measure the speed of a fluid, by measuring pressure changes at different segments of the device. When fluid flows though a Venturi the pressure in the two ends of the tube will differ, directing the fluid to the "low pressure" portion of the tube. The amount of motion can be calibrated to the speed of the fluid flow
