460 mm .The peripheral speed is 30 mls.The throat size is 50 14 cm for a 13-mm theoretical
length of cut with corn silage, which its density was 320 kg \m
i- calculate the linear speed of the feed mechanism.
ii- calculate the rated capacity in mega grams per hour , at 100% field efficiency
( Assume rated capacity = 70 % of theoretical ).
Q3: a) Calculate the fuel cost per hectar for cross fiaming cotton at speed of 6.5 km/ hr. Each
burner uses( 11) liter /h of fuel which cost ( 11g/ liter). Row spacing is 102 cm. Assume that
the field efficiency is 80 % and that the burners are off for 10 % of the total field time , then
determine the area in hectar /h can be covered with a 4- row machine.
b) What are the functional components of a plunger- type field baler.
