A 60-cm-high, 40-cm-diameter cylindrical water tank is being transported on a level road. The highest acceleration anticipated is 4 m/s^2. Determine the allowable initial water height in the tank if no water is to spill out during acceleration.

Respuesta :

Answer:

[tex]h_{max} = 51.8 cm[/tex]

Explanation:

given data:

height of tank = 60cm

diameter of tank =40cm

accelration = 4 m/s2

suppose x- axis - direction of motion

z -axis - vertical direction

[tex]\theta[/tex] = water surface angle with horizontal surface

[tex]a_x = [/tex]accelration in x direction

[tex]a_z = [/tex]accelration in z direction

slope in xz plane is

[tex] tan\theta = \frac{a_x}{g +a_z}[/tex]

[tex]tan\theta = \frac{4}{9.81+0}[/tex]

[tex]tan\theta =0.4077[/tex]

the maximum height of water surface at mid of inclination is

[tex]\Delta h = \frac{d}{2} tan\theta[/tex]

            [tex] =\frac{0.4}{2}0.4077[/tex]

[tex] \Delta h  0.082 cm[/tex]

the maximu height of wwater to avoid spilling is

[tex]h_{max} = h_{tank} -\Delta h[/tex]

            = 60 - 8.2

[tex]h_{max} = 51.8 cm[/tex]

the height requird if no spill water is [tex]h_{max} = 51.8 cm[/tex]
