Carbon dioxide at a temperature of 30°C and at a pressure of 580kPa absolute, with a gas constant of 288N-m/kg-°K. A. What is the unit weight of the carbon dioxide in N/cu.m B. What is the mass density of the carbon dioxide in kg/cu.m

8. The speciflc volume of steam at atmospheric pressure and 212 deg. Fahrenheit Is 26.80 ft3/lb. Flnd Its density.

The wolrd's oceans contain approximately 1.35x1021L of water. what is this volume in km3?

In Figure below all fluids are at 20 deg.C. Determine pressure at point B, if pressure at point A is 150 kPa and weight of air is neglected. Use the table below for the densities at 20 deg.C.

piston, on which rests a weight. . A gas is confined in a 1.25(ft) diameter cylinder by a The mass of the piston and weight together is 250(lb.m). The local acceleration of grav- ity is 32.169(ft)(s)-, and atmospheric pressure is 30.12(in Hg). (a) What is the force in (lbf) exerted on the gas by the atmosphere, the piston, and the weight, assuming no friction between the piston and cylinder? (b) What is the pressure of the gas in (psia)? (c) If the gas in the cylinder is heated, it expands, pushing the piston and weight upward. If the piston and weight are raised 1.7(ft), what is the work done by the gas in (ft)(lbf)?

Please help me this question

Latent heat of fusion is the heat given up as a substance freezes. The latentheat of fusion for water is 144 British thermal units per pound (Btu/lb). Thismeans that 144 Btu are given up for each pound of water that freezes. Howmany British thermal units of heat are given up when 4,000 pounds of waterfreeze?

What is the weight of a 10-pound mass at standard gravity in Newton, dynes and pound-force?

Answer number 3

1. A special-purpose piece of laboratory glassware, called a pyncnometer; is used to measureLiquid densities. It has a volume of 25 cc, and a mass of 17 .24 g when it is full of air. Whenfilled with a liquid of unknown density, its mass = 45.00 g. What is the density of this liquid?How large an error do we make if we ignore the mass of the air that was in it when we weighed itand found m = 17.24 g?
