Hi students, let me explain you the question here.
00:03
So a cylindrical riser.
00:06
So here the shape of the riser, it is cylindrical riser.
00:10
So it is designed for sand casting mold.
00:15
Previous observation have indicated that mold constant, mold constant, this casting, that is equal to 3 .26 minutes per centimeter square.
00:29
There is cylinder for riser cylinder for riser it having diameter to height ratio that is equal to 1 .0 so here the diameter to height ratio height ratio it is 1 .0 so here we have to determine the diameter in centimeter in centimeter of the riser its solidification time given it is so it's solidification time it is given as 1 .2 minutes we have to assume here n is equal to two coming to the solution here so we have to use here corino's theorem to find out the diameter to hide to find out the diameter to find out the diameter to find out the diamem and height of the riser.
01:52
So in order to find out the diameter as well as the height of the riser here we have to use corinov's theorem.
02:01
So here mold constant it is given.
02:05
What is the mold constant? 3 .26 minutes per centimeter square and v by a ratio we have to calculate here...
