PROBLEMA 1-

FORMULA   PE=P/V                                                              

PE=2.70G/CM 3     =  PESO ESPECIFICO                  P=3,750 toneladas

V=        0.18M 3              VOLUMEN                               2.70x1/1000

                                                                                             2.7/.72+3.75kgx1000=3.750

 PROBLEMA  2-PRESION HIDROSTATICA                                    PH=(1025.)(9.8)(20)=20900M/ 2S

FORMULA = PH=SGH

PH=?           PRESION HIDROSTATICA                                                                      PH=20900M3

S=1025.             DENSIDAD

G= 9.8M/2S       gravedad

H= 20M              ALTURA DEL FLUIDO      

 

PRESION HIDROSTATICA

 FORMULA     PH=SGH           

PH=?                   PRESION HIDROSTATICA                                      PH=(1000)(9.8)(3810)=3733800 M/2S         

S=1000                DENSIDAD                                                                    PH=3733800M3

G= 9.8M/2S       gravedad

                                                                                                                                        ph=(1000KGM3) )G=9.8M/2S     (20)=9600M3                                                                                            

H=3810M           ALTURA DEL FLUIDO

 H=(20)

 

PROBLEMA  3-             viene siendo LA MISMA   PRESION                                                                                   

FORMULA    P=F/A                              P=29.4 CM2                         ( 6KGF)(9.8)/2=29.4            P=   29.4CM2                                                            (90KGF)

(9.8)/30CM 2)=29.4CM 2

F=6KGF                                                                                                          F=90KGF              

A=2CM 2                                                                                                         A=30CM2

Problema    4

F=950N

A=5CM                  950X4=3800

                            A2   3800/950N(5CM)=20

A2?

F2+3800

   PROBLEMA   5
