The in situ moist unit weight of a soil is 17.3 kN/m3 and the moisture content is 16%. The specific gravity of soil solids is 2.72. This soil is to be excavated and transported to a construction site for use in a compacted fill.

A car air-conditioning unit has a 0.5-kg aluminum storage cylinder that is sealed with a valve, and itcontains 2 L of refrigerant R1 34a at 500 kPa; bothare at room temperature 20'C.

What is Pressure measured from absolute zero pressure called?

What is the atmospheric temperature on Venus if the density is 67 kg/m^3 and the pressure is 9.3 mPa, absolute? Express in °C and °F. The atmosphere is composed of CO2.

g In evaluating independent projects, no incremental analysis is necessary between projects. Each project is evaluated separately from others, and more than one project can be selected.

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.

A scientist who is evaluating an ancient human skeleton for signs of vitamin and nutrient deficiency is conducting:
