Adisk shaped part is cast out of aluminum. diameter of the disk = 650 mm and thickness = 16 mm. if the mold constant = 3.2 sec/mm2 in chvorinov's rule, how long will it take the casting to solidify

Time for solidification of the casting is 186 sec.

Explanation:

Chvorinov's rule is used to find the solidification time for any casting shape.

Step1

Given:

Diameter of the disk is 650 mm.

Thickness of the disk is 16 mm.

Chvorinov's rule constant is 3.2 sec/mm².

Step2

Calculation:

Total volume of the disk is calculated as follows:

V= 5309291.585 mm³.

Step3

Total surface area of the disk is calculated as follows:

A= 696334.0117 mm².

Step4

Chvorinov's rule for time calculation is expressed as follows:

t=186 sec.

Thus, the time for solidification of the casting is 186 sec.

answer:

in baseband transmission the whole bandwidth of the cable is utilized by a single signal. eg.Ethernet is using Basebands for LAN.

In the broadband transmission, multiple signals are sent on multiple frequencies simultaneously using a single channel. eg.Digital Subscriber Line (DSL)
