A pump is partially submerged in oil and is supported by 4 springs. The oil has a specific gravity of 0.90, the weight of the pu

mp is 14.6 lb, and the submerged volume is 40 in3. What force is needed in the springs so that the pump will remain in static equilibrium

7 0

Answer:

Explanation:

submerged volume of pump = 40 x 12⁻³ ft³

density of oil = .9 x 62.4 lb ft⁻³ ( specific gravity x density of water )

mass of displaced oil = 40 x 12⁻³ x  .9 x 62.4 lb

= 1.3 lb

buoyant force = 1.3 lb

weight of pump = 14.6 lb

extra force needed for balancing pump by spring

= 14.6 - 1.3

= 13.3 lb .

A vessel is filled with a liquid of density 1900 kg/m3 . There are two holes (one above the other) in the side of the vessel. Li
FromTheMoon [43]

Answer:

110 meters is the distance where they will intersect

Explanation:

given,

liquid density = 1900 kg/m³

distance of upper hole = 19 m

distance of lower hole = 117 m

acceleration due to gravity  = 9.8 m/s²

the speed at each point

v = \sqrt{2gh}  

for upper hole  v = \sqrt{2\times 9.8 \times 19}  

                         v  = 19.29 m/s

lower hole    v = \sqrt{2\times 9.8 \times 117}  

                          v = 47.88 m/s

The path for each is parabolic

x = v t

y = \dfrac{1}{2}gt^2  

y = \dfrac{1}{2}g(\dfrac{x}{v})^2  

y = \dfrac{gx^2}{2v^2}  

we get

upper hole

y = \dfrac{9.8\times x^2}{2\times 19.29^2}= 0.0132 x^2  lower hole

y= \dfrac{9.8\times x^2}{2\times 47.88^2}=0.00214x^2  y for upper hole = 80 + y for lower hole

0.0132 x^2= 98 + 0.00214 x^2

0.0082 x^2 = 98

x = 109.32 meters

110 meters is the distance where they will intersect
