Doctors commonly used a syringe for drawing blood, this syringe commonly has an opening with a 0.514mm of diameter. Determine what is the pressure of the liquid coming out of the needle If a force of 5.5 N. is applied to the syringe,.?
An Hg manometer is attached to a vessel. Change in the height of the Hg =14.75 cm. an atmospheric pressure of 751.5 torr is measured by A barometer in the same room. compute the pressure of the system express your answer in kPa. suppose the force of gravity = 9.81 m/sec^2 , density of mercury =13600 kg/m^3.?
