Ответ:
Wartość siły nacisku wody na okno wynosi 150000 N.
The value of the water pressure force on the window is 150,000 N.
Explanation:
Kompletne pytanie
Okno okrętu podwodnego ma powierzchnię 0,3 m2 i znajduje się na głębokości, na której ciśnienie wywierane przez słup wody wynosi 500 kPa. Dokończ zdanie. Wartość siły parcia wody na okno wynosi.
Rozwiązanie
Ciśnienie wywierane przez siłę na pole powierzchni prostopadłe do linii działania tej siły jest określone wzorem
P = (F / A)
gdzie F = przyłożona siła, w tym przypadku siła nacisku wody na okno =?
A = Obszar, na który działa siła = Powierzchnia okna = 0,3 m²
P = 500 kPa = 500000 Pa
500,000 = (F/0.3)
F = 500,000 × 0.3 = 150,000 N
Mam nadzieję że to pomoże!!!
Complete Question In English
The submarine window has an area of 0.3 m2 and is located at a depth at which the pressure exerted by the water column is 500 kPa. Finish the sentence. The value of the water pressure force on the window is.
Solution
Pressure exerted by a force on a surface area perpendicular to the line of action of that force is given by the formula
P = (F/A)
where F = applied force, in this case, water pressure force on the window = ?
A = Area upon which the force is acting = Area of the window = 0.3 m²
P = 500 kPa = 500,000 Pa
500,000 = (F/0.3)
F = 500,000 × 0.3 = 150,000 N
Hope this Helps!!!
