The coefficient of discharge for an external mouthpiece depends upon
Answer: Option D
No answer description available for this question.

|Its D is 100 right. If length of mouthpiece is long then discharge of fluid tend to decrease.|
|Apcivilian. said: (Dec 11, 2016)|
|Q = 0.855a√2gh.
So it proportional to C.s.a of Mouthpiece.
So C is the correct answer!
|Adorn said: (Dec 14, 2016)|
|What is the correct one?|
|Jay Vyas said: (Mar 12, 2017)|
|Yes Ans C is correct.
It depends on the area of the external mouthpiece.
Q = 0.855a√2gh.

|Answer D is correct, in already above written discharge formula, You all are considering as constant value i.e .855, but if we take the length of mouth piece in consideration then, Cd will decrease with increase in length as it increases friction resistance value in the wall of the mouth piece.|

|That is discharge formula not of coefficient of discharge.|
|Arun K Singh said: (May 29, 2018)|
|What about internal mouthpiece?|

|What is mouth piece?|

Mouthpiece is something with which you talk to in case of a phone. It is located at the bottom of the phone. If the mouthpiece is long then the person you're talking to will hear you better which means better discharge of sound. Hence discharge is directly proportional to Length.

|The 0.855 is the value of the cd of the external mouthpiece.|
