Steel casting ρ = 7854 kg/m3 is to be produced with cylindrical hole. Diameter of cylindrical hole is 0.5 times the length of cylindrical hole. a sand core ρ = 1600 kg/m3 is used to produced cylindrical hole.Net buoyancy force acting on core is 15 N. Calculate the diameter (mm) of the cylindrical hole.
Enter numerical value using the virtual keypad. Round off where necessary.
