Take saturated steam at 1.01325 bars 100 degree C, hg and hg at 1.01325 bars at 150 degree C superheated steam and interpolate them to 110 deg C, should get the answer.

Bro i did that too but i still didnt get the ans leh . I didnt get 2696 . I get 2690 still
Maybe your teacher answer is based on a different steam table, anyway the answer is close enough, dun have to sweat over the small difference
Ok thank you
Bro help . Give 2 suggestions on how to improve the heat transfer rate and explain clearly . How leh this question 4marks . Help me pls
And give one example for evaporation and drying process
Generally you can just increase the surface area, or increasing the velocity of cooling fluid
Can give reason like for the thing u stated for the explanation part
And what is one example for drying and evaporation process . Pls helpnme
Increasing surface area of the system allows more heat to be transferred out, increasing cooling fluid flow removes heat faster, increases heat transfer coefficient. For evaporation, you can increase the surface area of the liquid to be evaporated and use a fan. For drying, you can increase the exposed surface of the material and use a hot air drier to blow over it
Bro u there ?
Bro help me please exam tomoro leh help pls liao . For fluidization
if mass of the catalyst particles increases , what will be the effect on the type of fluidization ?
if mass of the catalyst particles decreases , what will be the effect on the type of fluidization ?

Bro pls help me leh
Heavier particles will mean you need a higher flow rate to achieve fluidization of the particles. The opposite for a lower particle weights
The weight of the particles = buoyancy of the air flow, is the condition of fluidization.
What do you mean by fluidization type
The weight of the particles = buoyancy of the air flow, is the condition of fluidization.
What do you mean by fluidization type
Aggregative or particulative fluidization i think? I dont know leh sorry but pls help me . How to ans this question eh
It is a bit hard to help, because I dun understand the qn
I send you the full question here and if you are free can you help me . And dont delete this app cos i need your help sometimes .
Ok
I post alr at H2 math JC2
Pls help me cos tomoro exam . Sorry and thanks
Ok
Din see it
Have leh . Its under #H2math #JC2 #Singapore ?
Din see it
Have leh why u keep saying u dont see sia . If u go to the unanswered post u will see mine. Pls liao leh
When you posted it
2 hours ago . I even said part d) . How come i can see it posted liao leh :/ .
Really fun see, maybe you repost ba
Nvm i post it on the ans key alr leh . U click the post at the one we are talking here then u can see the ans section . Help me de :/
