Cel ćwiczenia: Celem ćwiczenia jest doświadczalne i teoretyczne wyznaczenie wartości naporu hydrodynamicznego na powierzchnie o różnych kształtach.

Schemat stanowiska:

0x08 graphic

0x08 graphic
Wzory wyjściowe:

Wzór dla przegrody płaskiej:

0x01 graphic

Wzór dla przegrody półkolistej:

0x01 graphic

Z równania Bernoullego :

Wzór na teoretyczny napór hydrodynamiczny dla przegrody płaskiej jest następujący:

0x01 graphic

Natomiast dla przegrody kulistej następujący będzie:

0x01 graphic

Przykładowe obliczenia:

Obliczenia teoretycznej wielkości naporu hydrodynamicznego dla przegrody płaskiej:

r= 996,232 kg/m³

q= 0,00019444 m/s

d= 0,006 m

h= 0,07 m

g= 9,80665 m/s²

0x01 graphic

Obliczenia teoretyczne naporu hydrodynamicznego dla przegrody kulistej:

0x01 graphic

Wyznaczanie wielkości naporu hydrodynamicznego dla przegrody kulistej(doświadczalnie):

Korzystając z reguły dzwigni otrzymujemy:

0x01 graphic

Podstawiając: Otrzymamy:

m=0,09 kg

g=9,80665 m/s²

l₁=0,03 m

l₂=0,07 m. .

Dla przegrody płaskiej :

m=0,06 kg , g=6,80665 m/s²

l₁=0,03 m

l₂=0,09 m.

Wnioski:

Gdy przepływ maleje to wielkość naporu hydrodynamicznego spada.
Napór na przegrodę płaską jest mniejszy niż na przegrodę kulistą.
Przepływ jest proporcjonalny do naporu.
Prędkość strugi przy wylocie jest większa niż przy przegrodzie.
Na wykresie widać ,że wyniki doświadczalne są mniejsze od teoretycznych.
Gdy struga nie dociera do przegrody, to siła naporu jest równa zeru.
