A 2.15-m3 rigid tank initially contains air whose density is 1.18 kg/m3. The tank is connected to a high-pressure supply line th

rough a valve. The valve is opened, and air is allowed to enter the tank until the density in the tank rises to 5.30 kg/m3. Determine the mass of air that has entered the tank.

Answer: The mass of the air that has entered the tank is 8.858kg

Explanation:

Before we can solve to obtain the mass of air that recently gained access into the tank, we must calculate the density of the air that just entered the tank. It is obtained by subtracting the previous density in the tank from the new density in the tank:

= 5.30kg/m^3 - 1.18kg/m^3

= 4.12kg/m^3

So, the density of the air that entered the tank recently is

4.12kg/m^3.

To find the mass of the air, we apply the formula for calculating density and make mass (m), the subject of the formula:

Density = mass/volume

Therefore, mass = Density × volume

The density of the air is 4.12kg/m^3.

The volume of the tank occupied by the air = 2.15m^3

Then, the mass of the air that just entered the tank is:

= 4.12 × 2.15

= 8.858kg

Answer:

The mass of air that has entered the tank is 8.86Kg

Explanation:

We are given:

Size of tank= 2.15m^3 density = 1.18kg/m^3  new density = 5.30kg/m^3

We first calculate the intial and final masses,

Therefore:

M_initial = p_initial * V

= 1.18 * 2.15 = 2.54

M_final = p_final * V

= 5.30 * 2.15 = 11.4

Therefore to find the mass of air inside the tank, we use:

ΔM = M_final - M_initial

= 11.4 - 2.54 = 8.86Kg

Therefore the mass of air inside the tank is 8.86Kg

Thepotemich [5.8K]

Answer:

Explanation:

In the first instance, you had a logic function, which you had derived using some sort of a truth table, then reduced it using K-maps, and finally derived the simplified logic. If you had used logic gates to implement the logic, the result would have been the fact that there were a lot of logic gates used. For example, for a function of 2 variables, we would need 4 AND gates and 1 OR gate. Thus, the resulting circuitry would have looked very complex.

Whereas, if you would use a microcontroller to implement the logic, all you need would be a piece of code to run the logic. There would either be minimum number of gates (or no gates at all, depending on the logic you wanted to implement).

Thus the microcontroller would make the circuit look a lot less complex. Making the design and texting simpler and since there are now fewer components to test. Microcontrollers is that on the same piece of silicon, you could embed a lot more complex logic or program, than using purely digital gates this is another good that comes with Microcontrollers.

A floor system has W24 x 55 sections spaced 8’-0"" o.c. supporting a floor dead load of 50 psf and a live load of 80 psf. Determ
galben [10]

Answer:

Load sup[port by beam is 1040 lb/ft

Explanation:

Given data:

dead load of floor is 50 psf

live load of floor is 80 psf

load per meter can be determined as

Load/mt length = load intensity × effective width

total load  = deal load + live load

                  = 50 + 80 = 130 psf

load /mt length =  130 × 8

                         = 1040 p/ft = 1.04 k /ft

hence load sup[port by beam is 1040 lb/ft
