what is the difference between s trap and p trap?

The "trap" is the bend in the pipe where the waste goes out of the toilet. ... An S-trap exits at the bottom of the toilet, and is designed to outlet directly through the floor, where a P-trap exits at the back of the toilet and is designed to outlet through a wall.

Radiant Plumbing Explains: What Are House Traps? House traps were originally designed to prevent sewer odors from escaping your drains and re-entering your home. A typical house trap (also known as a “p-trap”) looks like a “U” in your plumbing line.

The difference is that the chemicals on the P list are identified as acute hazardous wastes and those on the U list are identified as toxic wastes. Some chemicals on both lists may also be designated to have other properties. Wastes included on the P and U lists can be found in the regulations at 40 CFR § 261.33.

As they are normally referred, PNP and NPN sensors are both supplied with positive and negative power leads, then produce a signal to indicate an “on” state. PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state.

S waves are slower than P waves and they can only travel through solid rock. S waves move the particles it pushes through up and down or side to side (perpendicular to the motion of the S waves energy). The second link has very good animated illustrations of both movements.

A more humane and faster method than live trapping and killing is the use of a well-designed snap trap. ... Snap traps that are designed well and used properly, are consistently found to ensure a quick death to the mouse or rat and once cleaned, they can be reused.

Home extermination techniques vary from traps to baits. ... Glue traps are similarly used to trap mice but also require proper placement to be effective. Live traps require homeowners to dispose of captured rodents. All traps require an intimate knowledge of mouse habits and behavior to use them effectively.

VAR. S returns a different result than VAR. P, which treats the range of data as the entire population. The variance based on the entire population, using the VAR.

The main difference between P and NP charts is the vertical scale. P charts show the proportion of nonconforming units on the y-axis. NP charts show the whole number of nonconforming units on the y-axis.

PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state. ... NPN, or “sinking” output sensors, work in the opposite way, sinking ground voltage to an input when it's on.

According to the UPC, the difference between a grease trap and a grease interceptor is the flow rate of waste water the device can handle. Grease traps have a flow rate of less than 50 gallons per minute. Grease interceptors have a flow rate of more than 50 gallons per minute.

It has been observed that the transistors in the native substrate tend to have better characteristics than that was made in a well. Because p devices inherently have lower gain than devices, n well process amplifies this difference while a p-well process moderates the difference.

C-states are idle power saving states, in contrast to P-states, which are execution power saving states. During a P-state, the processor is still executing instructions, whereas during a C-state (other than C0), the processor is idle, meaning that nothing is executing.

Trapping rats is similar to trapping mice, but rats require larger traps, and they can be smarter about avoiding traps that don't entice them properly or scare them off somehow.

Magneto-optical trap, in which radiation pressure forces are working, is a dissipative (open) system. The energy once leaves the system, never comes back. That's why it is a non-conservative trap.

A beta has a negative charge such that the new isotope has one less neutron and one more proton than the original isotope. A positron has a positive charge such that the new isotope has one more neutron and one less proton than the original isotope.

Like positron emission, electron capture occurs for “proton-rich” nuclei that lie below the band of stability. Electron capture has the same effect on the nucleus as does positron emission: The atomic number is decreased by one and the mass number does not change. This increases the n:p.
