Answer:
net force acting on the floor is 100 kN
Explanation:
Given data:
dimension of floor = 2 m \times 0.5 m
we know that
Net force can be calculated as follow
Therefore net force acting on the floor is 100 kN
Answer:
Explanation:
Given that;
Thermal diffusivity
Thermal conductivity
Heat transfer coefficient h = ( we are to assume the imposed surface temperature ) = 20 W/m².K
Initial temperature = 150 ° C = (150+273) K = 423 K
Then coolant temperature with which the casting is exposed to = 20° C = (20+273)K = 293 K
Time = 40 seconds
Length = 20mm = 0.02 m
The objective is to determine the temperature at the surface at a depth of 20 mm after 40 seconds.
Bi == 0.02
For a wall at 0.2 Bi
Therefore;
