A tank 5 m high is half filled with water and then is filled to top with oil of density `0.85 g//cm^3` The pressure at the bottom of the tank, due to these liquids is |
|
Answer» Correct Answer - `462.5 g wt. cm^(-2)` `Pressure = ("total weight of water and liquid")/("base area of tank")` `A xx (500//2)xx1xx980` ` = (+Axx500//2)xx0.85xx(980)/(A) dyn e //cm^2` ` =(250 xx 980 + 250 xx0.85 xx 980)/(980)g" wt "cm^(-2)` ` = 462.5 g wt. cm^(-2)` Alternative method, Average density =` (0.85 xx 250 + 1 xx 250)/(500)` =` 0.925 g//c.c`. `P = h rho g = 500xx0.925 xx 980` `= 462.5 xx 980 dyn e//cm^2` ` =462.5 g wt. cm^(-2)` |
