What is the recommended oil and oil pressure of a 1989 Porsche 944 with about 120000 miles?
Use 20w50. Recommend Valvoline VR1--it's got a chemical that is good for the old seals. A lot of the "race" oils have the same. Dan
Where is the voltage regulator located in a 1991 Dodge Dakota?
Check on the firewall near the coil. the voltage regulator is internal with the ecu for this model truck...if you, like me, have had yours go bad (internally) you can optionally use an external regulator from your parts store, just ask them if they carry a vr32 or a vr1...both of which should work
What does code 91 mean on the intex salt water pool system?
Code 91 means your system is reading low salt. This does not mean to add salt, it means to check your salt level of the water (salinity) and to check your system because its major cause is the salty looking crusty crud buildup on one or both ends of the electrolytic plates. That buildup changes the resistance between the plates. The saltwater system uses a range of resistance values to determine the salinity of the water. Since the resistance has been changed, the device "thinks" (used very loosely) the water does not have enough salt, hence the Code 91. So clean the electrolytic plates with some form of acid or white vinegar(your choice) until the plates are shiney again. Do not scrape or scrub the plates as you might scrape off the titanium coating and damage the plates. I found this other "FIX" on the net ..... Another "CODE 91" fix was said a while back regarding resistors. pull off cover carefully, both the flow sensor and cell power cables exit the case making lifting the plastic case difficult but manageable. look for three adjustable resisters, one above the other. They are marked (or mine was) VR1, VR2,and VR3 on the circuit board. they were black and about the diameter of a pencil eraser with a small Philips (+) adjustable head. The head was locked with glue? but it can be scraped off. The original suggestion said to turn the VR1 resister a quarter turn CCW. This did not work for me but I added an additional quarter turn CCW (now half a turn CCW) and it is back working as it did originally.
What is the principle of operation of LDR?
Working of light dependent resistor This circuit explains the principle of operation of LDR (light dependence resistor). The circuit has various applications like shadow alarm, automatic night/morning lamp. LDR, an acronym for light dependent resistor is a resistor whose resistance is dependent on light. The resistance of LDR is of the order of Mega Ohms in the absence of light and reduces to a few ohms in presence of light. In this circuit when the light falls on LDR, the resistance of LDR becomes low and the entire voltage drop takes place across the variable resistance VR1 (10K). As a result the base of transistor (T1) gets high input and it gets biased thereby glowing the LED. When no light falls on LDR, the resistance of LDR becomes high so almost entire voltage drop takes place across it and the base of transistor is at low potential. So transistor does not gets biased nor it becomes conducting, hence switching off the LED. The sensitivity of the circuit can be adjusted by varying the preset VR1.

Why is it impossible for us to taste spicy foods despite the absence of a spicy taste zone in the tongue?
You mean why is it "possible" to taste spicy food despite absence of its "taste receptors" in the tongue. Well, its because spicy food contains capsaicin. It is an organic molecule found in chillis and peppers capable to producing a burning feeling upon tissue contact. This is due to it binding to a neuronal receptor VR1, allowing movement of ions and such would result in a burning sensory sensation. That is why "spicyness" can be felt even on your lips when eating spicy food.
What is voltage across the 6.7 ohm resistor in series circuit with 23.7 V battery and resistors of 22.7ohms 39.3ohms and 6.7ohms?
hey!! let's see how we can figure this out, cool?!let's label some things first.Vbattery = 23.7 VR1 = 22.7 ohmsR2 = 39.3 ohmsR3 = 6.70 ohmshere's a little diagram..GND-------[- Vbattery +]-----------[ R1 ]-------[ R2 ] -------[ R3 ]-----------GNDcurrent, I, will be flowing through this circuit.but which way?current flows out of the + part of the battery.so real fast, let's add something to the diagram, cool?I------------>GND-------[- Vbattery +]-----------[ R1 ]-------[ R2 ] -------[ R3 ]-----------GNDI
Oil weight on Porsche 944 1988?
I bought my 1988 944 Turbo and it was using a lot of oil--about 1 liter per 500 miles. I changed the oil and put in a recommended Valvoline race oil (VR1) 20w50. It almost completely stopped using excessive oil--only about 1 liter every 1000 miles or more. This is factory spec (1-1.5 liters every 1000 miles is normal usage). Apparently, these older motors love the heavier stuff. And the race oil has this chemical that's good for the seals (not sold in "off-the-shelf" reg oil). I'm guessing the previous owner was running some modern, light oil like 5w30 synthetic. Good luck, Dan
Why do jalapenos burn skin?
The burning chemical in peppers of the genus Capiscum is capsaicin. It's a strong mucous membrane and skin irritant, and also a neural agent. Molecules of capsaicin bind with the neurosensors that detect abrasion and heat, hence the association between peppers and burning sensations. The exact mechanism of irritation seems to be stimulation of the aforementioned neurochemoreceptor, VR1. This compound is non-water soluable, and as such is difficult to remove. One of the best ways seems to be exposure to the protein casein, common in milk, to which capsaicin seems to readily bond (so you can drink milk to overcome the burning sensation -- somewhat). In ecology, the capsaicin is an irritant only to mammals. With birds, it produces an analgesic effect and in fact birds are the ones that spread Capiscum seeds. Seeds passing through mammal GI tracts fail to germinate, so this clearly is an evolutionary feature that deters mammals from eating these fruit. Capsaicin is also the active ingredient in Pepper Spray, the non-lethal weapon. It's severe enough that the use of pepper spray is banned in military operations. Capsaicin is also now used in a weird variety of pharmaceutical applications ranging from pain control (!) to oncology.
How does LDR work for street lights and explain with the help of circuit diagram?
Active light control by LDR and BC337This is automatic light circuit when be become dark. It by use LED Lamp, be a place gives the light and this circuit has small-sized use volt supply 3V only.The work of the circuit be when there is the light affects LDR1 will valuable the resistance at LDR1. It be down make Q1 work be born volt at fall straddle a pin C of Q1 compare with Ground be valuable a little more voltage bias to make Q2 work. By have D1 serial with a pin B of Q2 make volt at pin C of Q1 compare with ground must use volt about 1.4V arrive at make Q2 work. But when LDR1 no the light will make to is valuable the resistance more and more until make to have no current flow get along well with B of Q1 make Q1 do not work. Then have current flow through R1,D1 get along well with pin B of Q2 work cause LED1 stick bright. The part , VR1 , parallel connection with , LDR1 , as a result , for take keep fine the rapidity in taking light of LDR1
The total resistance in a series connection is equal to product of the individual resistance?
Yes. Power(P)=Current(I)xVoltage(E) or P=I x E, and since in a series circuit current is constant and voltage is additive then: P(series)=Pr1+Pr2+Pr3........ Actually, power dissipated in series circuits is P = I^2 * R and in parallel power dissipated = V^2/R
