Correct viscosity of furnace oil at the burner tip for proper atomisation is about 25 centistokes. To reduce the viscosity of high viscosity furnace oil (250 centistokes) to the correct atomisation viscosity (i.e. 25 cst), it should be preheated to about____°C.
In Newton's law of viscosity, which states that the shear stress is proportional to the __________ co-efficient of viscosity is called dynamic or absolute viscosity (where, V = velocity, $${{\text{V}}_{\text{g}}}$$ = velocity gradient).
A high viscosity index indicates relatively ____________ changes in viscosity of the oil with the temperature.
A resistance R is measured using the connection shown in the below figure. The current measured is 10 A on ranges 100A and the voltage measured is 125 V on 150 V range. The scales of the ammeter and voltmeter are uniform. The total number of scale divisions of the ammeter is 100 and that of the voltmeter is 150. The scale division can be distinguished. The constructional error of the ammeter is ± 0.3% and that of voltmeter±0.4%. The resistance of the ammeter is 0.25 Ω. The possible error in the measurement of R is?
Two sides of a rectangle were measured. One of the sides (length) was measured 10% more than its actual length and the other side (width) was measured 5% less than its actual length. The percentage error in measure obtained for the area of the rectangle is :
