QUESTION: 1. Determine physicochemical parameters for Palm Oil Mill Effluent (POME)‚ fresh empty fruit bunch(EFB)‚ and palm oil boiler ash. State the reference(s). 2. Determine the mass of each components at initial raw compost mixture that consist of POME+EFB(300metric ton)+ash+additive. Stat your answer in metric ton and consider any nutrient losses. The final compost should have: C/N<30‚ N=1.8%‚ P=0.5%‚ K=3.4%‚ Mg=0.8% Given: a) Composting time: 45 days b) Composting system:

energy are kinetic energy and potential energy. Kinetic energy is the energy of motion. A ball has kinetic energy when it flies through the air. The ball has the ability to do work in that it can act upon other objects with when it collides. Potential energy is stored energy that objects have because of their position. A cup on a table has potential energy: If you knock the cup off the table‚ gravity will accelerate the cup‚ and its potential energy will convert to kinetic energy. Kinetic energy is

ignition temperature 7 TYPES OF COMBUSTION: 6 SPONTANEOUS COMBUSTION : When a substance suddenly bursts into flame at room temperature‚ without application of a cause(heat)‚ it is called spontaneous combustion . Ex burning of phosphorus‚ sodium in air‚forest fires 7 RAPID COMBUSTION: When a substance burns rapidly ‚on application of heat and produces heat and light it is rapid combustion. Ex burning of petrol‚ LPG 8 SLOW COMBUSTION: When a substance burns in oxygen slowly

The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

and its kinetic and potential energy. The kinetic energy of the canister gives you a minimum value for the chemical energy of the combustion reaction. It is a minimum value because energy is lost as heat‚ friction‚ and in other ways. As you work through the procedure‚ consider where the energy is flowing. The overall flow of energy when the canister is launched straight up follows this sequence: Chemical energy: Energy released as heat causes an abrupt pressure rise in the canister. Kinetic energy:
