Design of Gating System-2

[@kamanamulenga3844]

wonderful lecture

[@alexarriaza4016]

Sir, this was an awesome video! Thanks a lot for sharing!

[@anandh1967]

for pressurized gating system area decreases from choke to gate than the ratio of the gate will be less than choke i.e less than one?

Great

pouring time was 23.....but u substituted 19....

[@debottambhowmik5102]

exactly same doubt bro!!

[@greatkalai8982]

s same doubt

[@bennykarunakar73]

Dear friends, It was a mistake. Instead of 23 seconds, it was typed as 19 seconds. Sorry for the typing error.

[@bennykarunakar73]

Please consider it as 23 seconds.

I am a die hard fan of NPTEL videos, but I got to know that pouring time for bottom gate system is not derived, nor was it mentioned. These points are very important from an engineer's perspective. I just want the forum to develop and please don't consider that I am picking up the drawbacks. There are some people who depend completely on these videos to know their syllabus. They may loose track!

Thank you Prof for your lectures , how do you calculate the pouring time if the cast material is Aluminum ?

[@mechanicalgroup4344]

Sir please upload vedioes on physicalmetallurgu

Jaroor apload karenge

Tqsm sir 👍

[@pranavpatil7561]

Thanks Sir

[@Praveenstein]

the cross sectional area for pressurized gating system decreases rite?...but the given ratio seems to increase...like for gray cast iron its 1: 1.3: 1.1 ...???anybody wanna sort it out????

[@manojpolawar7195]

Yeah

[@ravisevak]

See when a size of ingate is lesser than that of runner it will create back pressure and so it can be called pressurized gating system.
