Question

ciśnienie atosferyczne wynosi 10Pa na 1m2 ........................ ile to N 2. 4000PA ile to hPa 3. parcie wynosi 1000hPa na 1m2 ile to kN

Answer 1

1 Pa = 1 N/1m²

1 hPa = 100 Pa

1 kPa = 1000 Pa

1 MPa = 1 000 000 Pa

 

 

1.

p = 10 Pa

S = 1 m²

 

p = F/S  I*S

F = p*S 

F = 10Pa*1m²

F = 10 N

------------

 

2.

4000Pa = 40 hPa 

--------------------------

 

3.

p = 1000 hPa = 100 000 Pa

S = 1 m²

 

p = F/S  I*S

F = p*S

F = 100000Pa * 1m² = 100 000 N

F = 100 kN
