I'm guessing you're talking about a disc viscometer, in which case the higher the viscosity, the higher the measured torque.

What is the torque speed characteristic?
the ratio of the relative speed of stator magnetic field with the speed of rotor, to the speed of rotor is defined as slip. where as in torque slip characteristic is the graph between the speed of the rotor and the torque experienced on the rotor. in the case of induction motor, the torque decreases with the increase in the rotors speed. while in the case of sychronous motor, its different (you check out, because i just forgot about it!! keep smiling!
Performance curve of a single phase induction motor?
The performance curve can be a graph of torque versus speed. The torque is zero at zero speed and also at the synchronous speed. Normally an induction motor operates at 90-97% of the synchronous speed, where the slip is between 10% and 3%. In this region the torque is proportional to the slip. As the torque is increased the speed falls until the motor stalls and the speed drops to zero. Below the stalling speed the torque rises between zero speed and the stalling speed. Because the torque is 0 at 0, a single-phase induction motor needs a separate starting winding fed by a starting capacitor to produce a little positive torque that starts the motor.
Why high starting torque is required for trains?
because train has heavy mass & due to heavy mass inertia is also very high so more effort is required getting motion in train. it is also known that any type of motor required more initial torque for come in speed.
What three factors determine the amount of torque produced by an AC induction motor?
Torque is produced by a phase difference between two windings. The higher the phase difference, the higher the torque.The rotor rotates slightly slower than the magnetic field produced by the stator (the fixed winding). The difference in speed is called the slip and it allows low-frequency currents to be induced in the rotor and torque to be produced. For a motor rotating just below the synchronous speed, the torque is proportional to the slip which is defined by this, where Nis the actual speed and Ns is the synchronous speed:s = 1 - N/Ns
Drawing of speed-torque curve for synchronous machine?
Theoritical torque speed curve for a synchronous machine will be a vertical line located vertical to the synchrounous speed at x axis, from starting torque to stalling torque value. This is because theoritically synchronous motors are not self starting. Practically however they start as induction motors and at near synchrounous speed the excitation is switched on. Anand Sekhar
What is the relationship between torque and speed for an electric motor?
Torque and speed are inversely proportional
What is difference between speed and torque?
speed= distance per seconds & torque= revolution per seconds

What is ment by the term torque multiplication?
Torque multiplication is proportional to the difference in speed between the impeller and the turbine. for example : At an engine speed of 2100 RPM, and torque at that speed of 100 Newton meters, the torque input to the transmission will be 2.2 times that value - 220 Newton meters with help of torque multiplication.
What kinds of trains are there?
speed trains and trains to transport people

What are the differences Between Japanese Shinkansens and European High Speed Trains in terms of how the train is controlled?
The difference between Japanese Shinkansens and European High Speed Trains is that the European High Speed Trains make use of European EC Directive 96/48 while the Japanese Shinkansens use an ATC (Automatic Train Control) system.
What is relation between speed of generator and its voltage and torque on generator shaft and current produced by generator?
power = torque * rpm
What is the difference between speed and torque control?
Your question is wonderful .... But we are not intelligent enough to answer it ....
What is the torque on a torque converter?
Torque output of the engine at that speed.
Can other trains in Britan and Scotland travel faster than trains in the High Speed 1?
No, the other trains in Britain and Scotland cannot travel faster than the trains in the high speed one.
What is the difference between electromagnetic torque and load torque in electrical machines?
Electromagnetic torque and load torque are different.Electromagnetic torque is the torque that is produced inside the machine which makes the machine rotate,while load torque is the torque that is applied externally with brake drum and and spring balance.Electromagnetic torque can be varied by varying the speed of the machine,but load torque is fixed.
