Outside air at 50°f, 1 atm, and 40% relative humidity enters an air-conditioning device operating at steady state. liquid water is injected at 45°f and a moist air stream exits with a volumetric flow rate of 1000 ft3/min at 90°f, 1 atm and a relative humidity of 40%. neglecting kinetic and potential energy effects, determine a. the rate water is injected, in lb/min.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
