Blood flow streamlines through from the left ventricle into the aorta can be modeled as a reducing nozzle. Model both the left ventricle and the aorta as a tube with diameter of 3.1cm and 2.7cm respectively. The pressure in the left ventricle is 130mmHg and the pressure in the aorta is 123mmHg. Blood is ejected from the left ventricle at a speed of 120cm/s. Calculate the difference in height between these two locations.
