Air at a temperature of 333 °C flows with a velocity of 10 m/s over a flat plate 0.5m long. Estimate the cooling rate per unit w
idth of the plate needed to maintain the plate at a surface temperature of 27 °C. Properties of air: kinematic viscosity 5.21×10-4 m2/s, thermal conductivity 36.4×10-3 W/m∙K, Prandtl number 0.687.

Answer:
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
= water surface angle with horizontal surface
accelration in x direction
accelration in z direction
slope in xz plane is
the maximum height of water surface at mid of inclination is
the maximu height of wwater to avoid spilling is
= 60 - 8.2
the height requird if no spill water is
