Find the Viscosity Index of a fluid that has a viscosity of 32 cSt at 40 degrees C. The O VI and 100 VI reference fluids have viscosities of 110 and 50 cSt respectively, at 40 degrees C.

Exercise 2: Ventilation Requirements. In order to calculate the quantity of ventilation air needed for habitation, we need considering: V The CO, production P m3/s, and for this example, of a sedentary adult. V The concentration Cs% of CO,% in outdoor air, and V The maximum threshold CO, concentration Cr% for the occupied space. Normally, P = 4.7x10-6 m³/s per person, Cs =0.03% and Cr =0.5%. %3D If the flow rate, Q m³/s is the rate of fresh air flowing through a room to provide acceptable conditions, a CO, balance can be made.

If you were to break the 64 mm capillary in half and repeat the flow rate measurement with water, how would your measured values change?

A block of wood floats in fresh water with 0.604 of its volume V submerged and in oil with 0.927 V submerged. Find the density of (a) the wood and (b) the oil. (a) Number i Units (b) Number i Units

Assume that a raindrop has a volume of 0.05 cm^3 and you need an Avogadro's number of raindrops to fill up the cubic water tank. What is the length of the edge of the tank?
