determine the volume in ft3,of 2lb of a two-phase liquid-vapor mixture of regrigerant 134a at 40f with a quality fo 20%. what is the pressure in lbf/in2\
Pressure is measured in PSI, which is equal to the amount of force (lbf) that is applied per unit of area (in2).
This is demonstrated by the equations below. Simply multiplying the pressure by the area over which the force is exerted will convert PSI to pounds. In various system of measurement, such as English engineering units and British gravitational units, a pound-force (lb, lbf) is a unit of force. It has the same force as one pound of mass does in a typical gravitational field. A unit of pressure or stress based on avoirdupois measurements is the pound per square inch, or more precisely, the pound-force per square inch (symbol: lbf/in2; abbreviation: psi). It is the pressure that results from applying one pound of force.

a natural deposit of soil is found to have a water content of 20% and to be 90% saturated. what is the void ratio of this soil?
The void ratio of the soil is 0.3125 if the soil has a water content of 20% and is 90% saturated.
The void ratio of soil is the ratio of the volume of voids (empty space) to the volume of solids in the soil. It can be calculated using the following formula:
Void ratio = Vv / Vs
where Vv is the volume of voids and Vs is the volume of solids.
We know that the soil is 90% saturated, which means that 90% of the voids are filled with water. Therefore, the volume of voids filled with water is 0.9 * Vv, and the volume of voids not filled with water is 0.1 * Vv.
We also know that the water content of the soil is 20%, which means that 20% of the total volume of the soil is water. Therefore, the volume of water is 0.2 * (Vv + Vs), and the volume of solid is (1 - 0.2) * (Vv + Vs) = 0.8 * (Vv + Vs)
Now we can substitute the values of the volume of water and solid in the void ratio equation
Void ratio = Vv / (0.8 * (Vv + Vs))
We can solve the above equation for Vv and plug in the values of the water content,
Vv = (0.2 * (Vv + Vs)) / (1 - 0.2) = 0.25 * (Vv + Vs)
Now we can substitute this value in the void ratio equation
Void ratio = 0.25 * (Vv + Vs) / (0.8 * (Vv + Vs)) = 0.25 / 0.8 = 0.3125
So the void ratio of this soil is 0.3125.

The reactor volume is 450 m and the volumetric flow rate of the single inlet and exit is 40 m3/day. The inlet industrial waste concentration is 70 mg/L. a. What is the outlet concentration? b. The wastewater treatment plant engineers need to shut down the reactor for maintenance. Starting at time t=0, the concentration, Cin, entering the CSTR is set to zero. What is the outlet concentration as a function of time after the entering concentration is set to 0? c. How long does it take before the concentration in the tank reaches 15% of its initial steady-state value?
According to the problem the outlet concentration is 70 mg/L..
What is concentration?Concentration is the act of focusing one's mental energy and attention on a particular task, activity, or object. It requires directing one's thoughts away from distractions and towards a specific goal.
a. The outlet concentration can be calculated using the equation C_out = C_in*e^(-kt), where C_in is the initial concentration of the industrial waste contaminant (70 mg/L), k is the first-order reaction rate constant (0.22 day^-1), and t is the time in days. Plugging in the given values yields C_out = 70 mg/L * e^(-0.22*t). At t = 0, the outlet concentration is 70 mg/L.
b. The outlet concentration as a function of time after the entering concentration is set to 0 can be calculated using the equation C_out = C_in*e^(-kt), where C_in is the initial concentration of the industrial waste contaminant (0 mg/L), k is the first-order reaction rate constant (0.22 day^-1), and t is the time in days. Plugging in the given values yields C_out = 0 mg/L * e^(-0.22*t). At t = 0, the outlet concentration is 0 mg/L.
c. The time it takes for the concentration in the tank to reach 15% of its initial steady-state value can be calculated using the equation t = -ln(0.15)/k, where k is the first-order reaction rate constant (0.22 day^-1) and ln is the natural logarithm. Plugging in the given values yields t = -ln(0.15)/0.22 = 3.07 days.

The reactor volume is 450 m and the volumetric flow rate of the single inlet and exit is 40 m3/day. The issue states that the concentration at the outlet is 70 mg/L.
What is a concentration?Focusing one's mental energy and attention on a single activity, object, or task is known as concentration. It requires focusing on a specific objective rather than being distracted by other things.
a. The equation C_out = C_in*e(-kt), where k is the first-order reaction rate constant (0.22 day-1), C_in is the initial concentration of the industrial waste contaminant (70 mg/L), and t is the time in days, can be used to calculate the outlet concentration. C_out = 70 mg/L * e(-0.22*t) is the result of plugging in the given values.
b. The equation C_out = C_in*e(-kt), where C_in is the initial concentration of the industrial waste contaminant (0 mg/L), k is the first-order reaction rate constant (0.22 day1), and t is the time in days, can be used to calculate the outlet concentration as a function of time after the entering concentration is set to 0. C_out = 0 mg/L * e(-0.22*t) is the result of plugging in the given values.
c. The equation t = -ln(0.15)/k, where k is the first-order reaction rate constant (0.22 day-1) and ln is the natural logarithm, can be used to calculate the amount of time it takes for the concentration in the tank to reach 15% of its initial steady-state value at t = 0. When the given numbers are added up, the result is t = -ln(0.15)/0.22 = 3.07 days.
