In fluid mechanics, pressure head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It may also be called static pressure head or simply static head (but not static head pressure). Mathematically this is expressed as: where Note that in this equation, the pressure term may be gauge pressure or absolute pressure, depending on the design of the container and whether it is open to the ambient air or sealed without air.

  • In fluid mechanics, pressure head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It may also be called static pressure head or simply static head (but not static head pressure). Mathematically this is expressed as: where is pressure head (which is actually a length, typically in units of meters) is fluid pressure (i.e. force per unit area, typically expressed in pascals) is the specific weight (i.e. force per unit volume, typically expressed in N/m3 units) is the density of the fluid (i.e. mass per unit volume, typically expressed in kg/m3) is acceleration due to gravity (i.e. rate of change of velocity, expressed in m/s2). Note that in this equation, the pressure term may be gauge pressure or absolute pressure, depending on the design of the container and whether it is open to the ambient air or sealed without air.

Dapat juga disebut Pressure head statis atau hanya head statis saja. Secara matematis dinyatakan sebagai: arti simbol adalah pressure head (ukuran panjang, biasanya dalam satuan meter) adalah tekanan fluida (yaitu daya per unit area, biasanya dalam hukum Pascal), adalah (berat per unit volume, biasanya dalam N/m³ unit) adalah densitas fluida (massa per satuan volume, biasanya dalam kg/m³) adalah (laju perubahan kecepatan, dinyatakan dalam m/s², dan di Bumi biasanya dinyatakan sebagai 9,81 m/s²) Catatan: dalam persamaan ini, istilah tekanan dapat mengacu pada atau , tergantung pada desain wadahnya dan apakah dalam keadaan terbuka terkena udara disekitarnya atau disegel tanpa udara.

Ele é matematicamente expresso: onde: é a cabeça de pressão(comprimento, (tipicamente a unidade de m); é o fluido pressurizado (força por área, como unidade Pa ); e é a peso específico (força por unidade de volume, tipicamente a unidade N/m3 ) é a densidade do fluido (massa por volume, tipicamente kg/m3) é o aceleração da gravidade (taxa de variação da velocidade, dado por m/s2) Observe que esta equação, o termo pressão é a Psi (medida de pressão), não pressão absoluta.
