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

can this be done using simpsons rule?
An exponent, such as the 4 in the expression 94, means: the number of times the number before the exponent is multiplied by itself (9 x 9 x 9x 9). O the number of times the number before the exponent is multiplied by 10 (9 x 10 x 10x 10 x 10). O the number to multiply the first number by (9 x 4). O the number of times the digit is written (9999). the number lo add to the first number (9 +4).

LESSON: AUTODESK AUTOCAD Choose from the choices:
Write TRUE is the statement/s is True. If the statement is false, identify the word/s that makes the sentence incorrect and write its corresponding correct answer. 1. High cutting temperature is undesirable because it reduces tool life, produces hot chips and can cause inaccuracies in tool dimension due to thermal expansion. 2. Cubic boron nitride does chemically react with iron and nickel. 3. Nose wear is usually caused by rubbing of the tool along the machined surface of the workpiece.
