Technician A says that squeeze-type resistance spot welding (STRSW) may be used on open butt joints. Technician B says that repl

Mamont248 [21]

Answer:

B only

Explanation:

Squeeze-type resistance spot welding (STRSW)is a type of electric resistance welding that brings about the weld on interfacing sheet metal pieces through which heat generated from electric resistance bring about fusion and welding of the two pieces together

Therefore, it is not meant for opening but joints but it can be used for making replacement spot welds adjacent to the original spot weld due to the smaller heat affected zone (HAZ) created by the STRSW process.

A rigid tank holds 22 kg of 127 °C water. If 9 kg of that is liquid water what is the pressure in the tank and volume of the tan

ipn [44]

Answer:

The pressure and volume of the tank are 246.878 Kpa and 9.449 m³ respectively.

Explanation:

Volume is constant as the tank is rigid. Take the saturation condition of water from the steam table for pressure at 127°C.

Given:

Total mass of water is 22 kg.

Mass of liquid water is 9 kg.

Temperature of water is 127°C.

From steam table at 127°C:

The pressure in the tank is 246.878 Kpa.

Specific volume of saturated water is 0.00106683 m³/kg.

Specific volume of saturated steam is 0.72721 m³/kg.

Calculation:

Step1

From steam table at 127°C:

The pressure in the tank is 246.878 Kpa.

Step2

Dryness fraction is calculated as follows:

$x=\frac{m_{v}}{m_{t}}$

Here, dyness fraction is x, mass of vapor is $m_{v}$ and total mass is $m_{t}$ .

Substitute the values in the above equation as follows:

$x=\frac{m_{v}}{m_{t}}$

$x=\frac{22-9}{22}$

x = 0.59

Step3

Specific volume of tank is calculated as follows:

$v=v_{f}+x(v_{g}-v_{f})$

$v=0.00106683+0.59(0.72721-0.00106683)$

$v=0.00106683+0.42842447$

v=0.4295 m³/kg.

Step4

Volume is calculated as follows:

$V=v\times m_{t}$

$V=0.4295 \times22$

V=9.449 m³.

Thus, the pressure and volume of the tank are 246.878 Kpa and 9.449 m³ respectively.

ryzh [129]

Answer:

an attachment is below

Explanation:

1) the formula for damping coefficient id for RLC series circuit.

For \xi =0 you can make c=0 but inductor will still have some capacitance.

2) the responses of critically damped system and under damped system are shown with comments on their time response.

4) There can be many different answers to this question, but the 4 I have mentioned are the most important parameters we need to know about an unknown op-amp if we are to use it in our circuit.

Hope it answers all your questions.
