In giving a patient blood transfusion the bottle is set up so that the level of blood is 1.3 m above the needle which has an internal diameter of 0-36 mm, and is 0-03 m in length. If 4-5 ce of blood passes through the needle in one minute calculate the viscosity of blood if density is 1020 kg m^(-3)

1.	In giving a patient blood transfusion the bottle is set up so that the level of blood is 1.3 m above the needle which has an internal diameter of 0-36 mm, and is 0-03 m in length. If 4-5 ce of blood passes through the needle in one minute calculate the viscosity of blood if density is 1020 kg m^(-3)
Answer» SOLUTION :V = ` 4.5 //60 = 0.075 cm ^(3)s^(-1)7.5 xx 10 ^(-8)m ^(3)s^(-1), p = 1.3 xx 1020xx 9.8 ` PASCALS ` eta = pi Pr^(4) //8vl = pi xx 1.3 xx 1020 xx 9.8xx (1.8 xx 10^(-4))^(4) //8xx 7/5 xx 10 ^(-8)xx 0.03 ` ` = 0.0024 ` DECAPOISE
