Calculate the solidification time (in minutes) of an alloy (AL-Si) with the following material data: 550°C melting temperature, 3.97x10^-5 J/kg latent heat, density of 2700 kg/m^3 and specific heat of 900 Jīkg*K. Metal casting is deposited in a cylindrical mould with dimensions: 30cm in diameter and 50cm in length. The mold is made of silica sand with thermal conductivity of 0.52 W/m*K, density of 1.6 kg/dm^3 and specific heat of 1170 J/kg*K. The pouring temperature is 700 °C in a mold that is at a temperature of 50 °C. Consider that the mold is closed. Answer is: t,= 23.78 min

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
