Zero, because it's at the far reaching point before going back the other direction.

Saturation temperature of steam is the Temperature at whihc any addition of heat does not increase the temperature of the water but produces steam.It depends upon the pressue and for every pressure there is a saturation temperature.

Take a normal pin and smack it on the head with a mallet a few times.

It has a flash point of about -50° F (-65° C)(lowest temp ignitable). The ignition temperature is about 495° or autoignition which it can go off without external spark source.

Horizontal or vertical gear shaping machines, they can also be made on slotting machines.

It is the maximum stress at which a material will fail when subject to flexural ( moment producing) bending loads. These stresses occur a the material outer fibers.

G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus

A refrigeration circuit is provided with a quench line connecting the liquid line and the suction line and containing a QEV. The QEV is controlled responsive to the superheat of the refrigerant supplied to the compressor. By injecting liquid refrigerant downstream of the suction modulation valve and the sensor for the TXV, the system can be operated at low capacity without overheating the compressor oil.

Well, most of the threaded fasteners used in general applications have the following disadvantages:

1. Continued exposure to vibration tends to loosen the fastener.

2. If the fasteners are not creep resistant, they will fail at elevated temperatures.

3. The sharp edges formed in the threads of the members acts as stress concentration regions and is undesirable. This is to some extent overcome by introducing a small radius at the crests and troughs of the threads.

The exhaust gases are often up to 500 Degrees C (940 Degrees F) but this can vary wildy depending mainly on load.

Your question is a bit to vague to cover everything. You'd need to be specific about the running conditions. High T5 can be caused by overload of the unit as well as a variety of fault conditions. If the unit is running in T5 control mode (ie: full load) and experiences alarms or trips, it may be that T5 gain and integral values need to be adjusted to smooth out the over-shoot. Make sure that the fuel supply pressure to the unit is stable as the fuel system will have to counteract any changes in flow due to oscillations in supply pressure. This can introduce instability in the loop leading to high T5. If the unit is running below T5 in speed control (NGP) and suddenly trips on a very fast rise in T5, it's worth checking the speed probe and connections all the way back to the card. If there's a downward spike in the sensed speed due to loose connection or poor probe gap adjustment, the control system will react by putting in extra fuel to try to get back to the set-point, causing high T5 trip. This will very often be too fast to pick up on HMI or trigger log. There can also be problems with fuel valves that can cause poor temperature stability. Injector fouling is another possibility if your fuel quality is poor. Have a look at the T5 spread to see if they are all reading close to the same value. In very hot climates where the air inlet temperature go very high in the Summer months, you will hit the T5 control mode limit earlier than when the T1 air inlet temperatures are lower.

Hope that this helps.

Whitworth quick return mechanism is a device where reciprocation motion in forward stroke is slower then the return stroke.

For pipe flanges the class rating is the pressure rating for the flange, in pounds per square inch - gauge (psig).

Calculating the friction loss in a pipe can be conducted using one of various equations which include, but are not limited to the Darcy friction factor and the Colebrook equation, and are attributed to the authors of the same.

The first thing to consider when determining friction loss is the type of flow in the pipe. There may be laminar flow or turbulent flow which both depend on the velocity of flow through the pipe. The Darcy equation is commonly used for laminar flow only where the Reynolds number is less than 2300, and does not provide accurate values for turbulent flow. The Colebrook equation will provide greater accuracy when flow is turbulent (Reynolds number > 4000) or neither laminar or turbulent (2300 < Reynolds number < 4000).

The next item to consider is the type of pipe through which the fluid is flowing. Different types of pipe have different profiles of roughness inside. The friction provided by this roughness will slow down fluid flow. There are constant values attributed to various types of pipe, and can be found in a fluid mechanics text.

Next consider the hydraulic diameter. This is the diameter of the pipe and varies depending on the shape of the pipe. Remember, not all piping runs are round. Air is considered a fluid and flows through square or rectangular "pipes".

Finally, friction loss will be affected by bends and obstructions in the pipe run. Tables are also available in your fluid mechanics text. Different types of bends and obstructions have different values and must be summed to provide the total loss through the pipe run.

When doing activities with a lot of turning or spinning, the person may become dizzy and lightheaded. To overcome this, the person should put their hands on their knees and breathe deeply, or sit down and breathe until the dizziness passes.
