How to check silo overflow to calculate the fiber loss

First you have to prepare some data for: 

How to check silo overflow to calculate the fiber loss
The data need to be taken:
1. level (%)
2. flow rate in ml / (1 / 1000) seconds on the conversion to liters / sec
3. data consistency (%)
4. Data ash content (%)
The data above is required to calculate the fiber loss (kg / day), ash loss / day

Supporting data for the parameters that need to be made is
1. pH
2 temperature (oC)

CHECK	25-26 Feb 11
	pagi	siang
Level (%)	94,5	94,5
flow rate (Liter/sec)	2.70	0.97
consistency (%)	0,25	0,27
ash (%)	34.13	36.00
	583	226
fiber loss(Kg/day)	384	145
ash loss(Kg/day)	199	81
pH	7.04	6.98
Temp	44	44

calculation

a. Calculate the fiber loss (kg / day)

Fiber loss = (Flow Rate x 60 x 1440 x% consistency) - ash loss

b. Calculate ash loss (kg / day)

Ash's loss = (Flow Rate x 60 x 1440 x% consistency) x ash content (%)
