Question 3 1 pts Calculate the mass of 23.5 cm3 of aluminum if the density is 2.70 g/ml
A cylindrical drum, 80 cm in diameter & 200 cm high, is filled with a fluid whose density is 640kg/m. Determine the mass of the fluid in kg.
1) A disk 40 cm in diameter and 5 cm thick is to be cast of pure aluminum in an open mold casting operation. The melting temperature of aluminum = 660°C, and the pouring temperature will be 800°C. Assume that the amount of aluminum heated will be 5% more than what is needed to fill the mold cavity. Compute the amount of heat that must be added to the metal to heat it to the pouring temperature, starting from a...
