On 6.1.2 what happened to the diameter of the ram ,you seem have just dropped it with π/4

[@edwardronekedzwa460]

Co ask

[@nthabelengmakete6134]

?

[@mathszoneafricanmotives]

Was a mistake on that one

[@Vendandihayani]

I saw it too it was a mistake just substitute without canceling pie over 4 ❤

[@ncutukazimbangatha7452]

So what will be the answer

[@lungelobuda9020]

Sir in 6.2 u are given N in r/min and question wanted the delivery per hour so I think u should convert N to r/hr coz if they said find the delivery per second u where going to use N in r/sec

[@mathszoneafricanmotives]

Let me check it

[@QueenLikhethe]

Why don't we multiple by 3600 to convert the volume in per hour? How is it already in per hour?

[@mathszoneafricanmotives]

Hie on which part exactly

[@marcaroughsecretagent.]

Sir what happened to D² the time you canceled pie/4 in 6.1.2?

[@mathszoneafricanmotives]

I made a mistake canceling the D^2

[@Tuber_ZA]

At which instances do we divide efficiency by 100, and where do we divide 100 by efficiency?

[@celestialxitshembiso3696]

I think you divide 100 by efficiency when you're calculating MA but when calculate volume it's efficiency divided by 100 and also power in you divide efficiency by 100

[@Tuber_ZA]

@@celestialxitshembiso3696 thank you🙏

[@Skouulazy]

How did u press the calculator in 6.2 to get that answer?

[@mathszoneafricanmotives]

Are you getting a different answer

[@thxbistones7004]

​@@mathszoneafricanmotivesyes

[@celestialxitshembiso3696]

​@mathszoneafricanmotives yes sir we're getting a different answer

[@aeternum911]

multiply by 60 the 333.33 instead of dividing

[@ncutukazimbangatha7452]

Im confused in 6.1.2

[@mathszoneafricanmotives]

Hie will work on similar questions to elaborate
