It plays a crucial role in many areas such as ventilation and cooling applications, but also power and energy technologies. Common uses are to calculate the air velocity by measuring the differential pressure with a pitot tube (prandtl tube). Other examples are operating rooms and clean rooms where some overpressure is needed for hygiene and safety reasons, to keep contaminants and bacteria etc. outside.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-divider stk-block-divider stk-block stk-0169bf8 avdelare\" data-block-id=\"0169bf8\"><style>.stk-0169bf8 hr.stk-block-divider__hr{width:100% !important;}.stk-0169bf8 {max-width:800px !important;min-width:auto !important;margin-right:auto !important;margin-left:auto !important;}<\/style><hr class=\"stk-block-divider__hr\"\/><\/div>\n\n\n\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-abc85bf\" id=\"fysiska-principer\" data-block-id=\"abc85bf\"><style>.stk-abc85bf {max-width:800px !important;min-width:auto !important;margin-right:auto !important;margin-left:auto !important;}<\/style><h2 class=\"stk-block-heading__text stk-block-heading--use-theme-margins\">Physical principles.<\/h2><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-dd9f494\" data-block-id=\"dd9f494\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-dd9f494-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-c14cc34\" data-v=\"4\" data-block-id=\"c14cc34\"><style>.stk-c14cc34-container{max-width:800px !important;min-width:auto !important;margin-right:auto !important;margin-left:auto !important;}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-c14cc34-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-c14cc34-inner-blocks\">\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-14148d2\" data-block-id=\"14148d2\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-14148d2-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-eb8d912\" data-v=\"4\" data-block-id=\"eb8d912\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-eb8d912-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-eb8d912-inner-blocks\">\n<p class=\"wp-block-paragraph\">Pressure is the force per unit area acting at each point inside a closed volume of gas or liquid and also against adjacent solid surfaces, e.g., the ground. the walls of a container.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The variable pressure (p) is defined as a force (F) that is uniformly applied to a given surface (A).

A distinction is made between different types of pressure, depending on the reference used. If absolute vacuum is used as a reference, an absolute pressure is measured. If the reference is instead the current ambient pressure, it is a negative or positive pressure (lower or higher than the ambient pressure).
