Aslurry containing 100 kg of fine particles per m' of water is filtered under constant pressure of 200 kn min a plate and frame press. in a lab scale experiment performed under constant pressure difference of 200 kn m produced flow of water through a filter cake of 1 cm volume was 0.03 cm's! the cake is incompressible and has a voidage of e=0.45. calculate: (1) the specific resistance of the cake for the lab scale experiment, r(m2); [10 marks] (ii) the thickness of the cake in a plate and frame press, l(m) formed after t=1000s of filtration (10 marks] additional information: • the resistance of the filter medium may be neglected, the viscosity of water is p =1 mns m? the density of the particles is p = 3000 kg m

i will, dm me on here.

explanation:

i need some with some bio stuff see if anyone will

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

girl imma just put my comment here because i need a couple point okurrttt
