4) A giraffe's head is 2.0 meters above its heart. The heart pushes a column of blood up to the head at a rate of 400 ml/min. Assume all of this blood passes through the carotid artery which has a diameter of 1.2 cm along it's entire length. (5 pts each) a) How much pressure does a column of blood that is 2.0 m tall exert at the level of the heart. You may assume that the column is cylinder and has a diameter of 1.2 cm if it helps Express your answer in pressure units of mig. (1. mmHg = 133 N/m^2, this is the pressure exerted by a column of liquid mercury thout mm tall) 133 (2m (1.2cm) 100cm mji (55oomHg b) What is the mass flow rate of blood in the carotid arom? Express your answer in kg/s. m=AvP 1.Oleg (1:7.com) hoegen ( (st you or intensy hoog) at leg 10bog Ibain teosec Too 182 man -4 c) What is the linear velocity of blood within the artery?

Potentially useful information: Turn moranes ahnut 280 mmH n = 9.8 m/s d) What is the kinetic energy rate of blood when it reaches the brain? Express your answer in Watts kinetic - mering im (Ep) Eett) = 400ml/min. Ep = 400 mL/min M T e) What is the change in potential energy rate of blood from the heart (initial) to the head (final)? Express your answer in Watts. + Em (ep ) + (6 + [w { 1) Assuming the kinetic energy rate of blood entering the heart is zero, what is the rate of work done by heart on the blood in moving 400 ml/min of blood to the head? Express your answer in Watts w w 40mL/min 5
