Blood plasma flows with a rate of 0.4 cm³/s through a tube with a diameter d = 0.18 cm and length I = 1.8 m at a temperature of 20°C. The pressure at the tube entrance is P2 = 1.48 x 104 N/m2. If the temperature of the tube and plasma reaches 29°C, what is the tube entrance pressure P2' needed to maintain the flow rate and pressure at the tube exit constant. Consider 120°c = 1.81 mPa·s and n29°c = 1.28 mPa.s.

Question
Blood plasma flows with a rate of 0.4 cm³/s through a tube with a diameter d = 0.18 cm
and length 1 = 1.8 m at a temperature of 20°C. The pressure at the tube entrance is P2 =
1.48 x 104 N/m2. If the temperature of the tube and plasma reaches 29°C, what is the tube
entrance pressure P2' needed to maintain the flow rate and pressure at the tube exit
constant. Consider 120°c = 1.81 mPa·s and n29°c = 1.28 mPa.s.
