Answer:
C = 0.3 F
Explanation:
The expression for a voltage in a capacitor with an initial voltage V₀, as a function of time, is given by the following equation:
When V = =.37*V₀, we have the following expression:
Applying ln to both sides, we have:
⇒ t = R*C
if t= 300 s, and R = 10³ Ω, we can solve for C as follows:
So, the required value for C is 0.3 F.
Answer:
The unit of 70.5 is lbm/ft^3
The unit of 8.27×10^7 is in^2/lbf
Explanation:
The unit of 70.5 has the same unit as density which is lbm/ft^3 because exponential is found of constant values (unitless values)
The unit of 8.27×10^7 (in^2/lbf) is the inverse of the unit of pressure P (lbf/in^2) because the units have to cancel out so a unitless value can be obtained. Exponential is found of figures with no unit
Answer:
Some of the irreversibilities are listed below:

- Transfer of heat over finite difference of temperature
- When two fluids are mixed together the process is irreversible
- Combustion of a gas
- Current flowing through a finite resistor
- Diffusion and free compression or expansion of gas
- Relative motion of body with force of friction
- Processes involving chemical reactions(spontaneous)
