Finding k1 and k2

Now the question is aries that how to find k1 and k2. We know from the previous blog entry that k1 is equal to 0.3d. Now finding k2 theoretical is not possible (equation is there, but it is not giving accuracy). So k2 always founded practically.
When a designer starts to make bansuri he always keeps length more then the theoretical length .
After making blow hole, he starts to tune bansuri to lower Pa. He reduces the length of bansuri and consistently checks the pitch. When he get the correct pitch,he checks the actual length on which he arrived. Now we know theoretical length, actual length and k1, we can find k2. Which we will use for our further calculation and tone hole placement and diameter finding.

K1 and K2

K1 is the end correction due to diameter of bansuri while k2 is end correction due to blow hole
Hence total end correction will be
Theoritical length-k1-k2 = Actual length
