Question

Question 1: A bitumen sample was tested to estimate its specific gravity. Knowing that: The weight of pycnometer The weight of pycnometer The weight of pycnometer without stopper 40.1g.including stopper -48.5 g+bitumen- 69.7g. The weight of pycnometer The weight of pycnometer Remark: (All weights are +bitumentwater 74.6g taken at 25 °C) a) Calculate the specific gravity of this bitumen? b) If you are planning to purchase a charge of this bitumen which will be transferred by a tank container with a capacity of 36 m2. What will be the charge weight and price of bitumen if 1 ton of bitumen costs S460?

Answer 1

The weight of pcynometer((w_1) = 40.1g The weight of pcynometer + bitumen(w_2) = 69.7g The weight of pcynometer + water(w_3) = 74.1g The weight of pcynometer + water + bitumen(w_4) = 74.6g weight of sample(bitumen) = w_2 - w_1 = 69.7 - 40.1 = 29.6g weight of sample(i e, w et bitumen) = w_4 - w_3 = 74.6 - 74.1 = 0.5g (a) Specific gravity of bitumen(G_b) = w_2 - w_1/(w_2 - w_1) + (w_4 - w_3) = 29.6/29.6 + (0.5) * G_b = 29.6/30.1 = 0.983 (b) from above data we have 0.983 gram = 1xm^3 = (36 times 10^6)vm^3 charge weight = 0.983 times 36 times 10^6/1 = 35 38 times 10^6gm Asymptotically Equal To 36 times 10^3kg Asymptotically Equal To 36tons for 1 ton bitumen = $460 36 tons = ? = 36 times $460 price of bitumen = $ 16560.
