Steam ships can burn diesel fuel. They burned residual because it cost less. The remaining few steam warships nowadays burn diesel fuel in most navies, for reasons of standardization of fuel with the greater number of gas turbine and diesel warships.
Answer by Anatomy James. Confidence votes 5.8K. The Chamber that creates the highest pressure is the Left Ventricle. It must do this to get the blood all the way around the body, including right up to the top of the heat, but more importantly it must overcome the huge pressure in the Aorta. This is because of the Aortic Valve which sits stops the blood being pushy back formthe aorta into the ventrivle.
As for your blood pressure, you tell me that the systolic pressures you measured are 183, 160 and 137. The systolic pressure is the pressure in the major arteries when the heart beats, and it tends to go up as you get older as the walls of the aorta and other big arteries become stiffer and less elastic.
