Chapter 1, Problem 2P

1. What is the weight in pounds-force of an object with a mass of 19 lbm on a planet where g = 12 ft/s2? 2. If a gas has γ = 14 N/m3, what is its density? State your answers in SI units.

The air pressure in an automobile tire is 35 psi. Express the pressure in appropriate SI units (kPa).

Represent the following combinations of units in the correct SI form:mN/kg.us

In medical work, pressures are often measured in units of mm of H2O because body fluids, including the cerebrospinal fluid, typically have nearly the same density as water. The pressure of the cerebrospinal fluid can be measured by means of a spinal tap. A hollow tube is inserted into the spinal column, and the height to which the fluid rises is observed. If the fluid rises to a height of 160 mm, we write its gauge pressure as 160 mm H2O.  (a) Express this pressure in pascals, in atmospheres, and in millimeters of mercury.

In other cases, a physician may suspect that a tumor or other growth is locking the spinal column and inhibiting the flow of cerebrospinal fluid. Such conditions can be investigated by means of the Queckensted test. In this procedure the veins in the patient’s neck are compressed, to make the blood pressure rise in the brain. The increase in pressure in the blood vessels is…

If under standard conditions a certain gas weighs 0.14 lb/ft3, then its corresponding specific volume, expressed in terms of cubic feet per slug (ft3 /slug), must be

Define the international system of units.

Handwritten and the unit should be in metric system. Three kilograms of water at 35 degrees Celsius are placed in a piston under 4.335MPa (State 1). Heat is added to the water at constant pressure until the piston reaches a stop at a total volume of 0.55 m3 (State 2). Most heat is added at constant volume until the temperature of water reaches 425 degrees Celsius (State 3). Determine (a) the quality of fluid and the mass of the vapor at State 2, and (b) the pressure of the fluid at State 3.
