Answer:
ρ=0.0102lbm/ft^3
Explanation:
To solve this problem we must take into account the equation of continuity, this indicates that the sum of the mass flows that enter a system is equal to the sum of all those that leave.
Therefore, to find the mass flow of exhaust gases we must add the mass flows of air and fuel.
m=0.59+60=60.59lbm/s( mass flow of exhaust gases)
The equation that defines the mass flow (amount of mass that passes through a pipe per unit of time) is as follows
m=ρVA
Where
ρ=density
V=velocity
m=mass flow
A=cross-sectional area
solving for density
ρ=m/VA
ρ=60.59/{(1485)(4)}
ρ=0.0102lbm/ft^3
Answer:
Quantity of heat or heat energy
Explanation:
the quantity of heat is the calculation of the total quantity of thermal energy in an object. it's S.I unit is joules (J) and the symbol for calculating it is Q.
Cell theory states that all living things are made of cells. And cells can only come from other cells, this disproves spontaneous generation and therefore proves the view that organisms can grow from food or dirt is wrong.
Answer:
solute + solvent = solution
Explanation:
solute is <em>Any substance that is dissolved in a liquid solvent to create a solution</em>
solvent is <em>A liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution.</em>
and.
solution is <em>A homogeneous mixture, which may be liquid, gas or solid, formed by dissolving one or more substances.</em>
