Want to dry the wet leather with 61% water to have moisture to 6% by weight by feeding into a continuous tunnel dryer if the mass flow rate of the leather bleach is 250 kg / h and enter dry air at 60 c, pressure 1 atm into the drying oven at 55 c, pressure 1 atm, relative humidity 50%. calculate.
1. the rate of feeding the bleach into the drying tunnel
2. volumetric flow rate of dry air inlet, m ^ 3 / h

did anyone actually do this? like if anyone has submitted this i rly need .

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
