In Marshall test, before testing the specimen in Marshall Machine to obtain its Stability , the specimen is submerged in the water bath at 60 o C for :a.30 minutesb.60 minutesc.Noned.80 minutes

In Marshall test, the loading rate is :a.0.05 inch/min.b.Nonec.2.0 inch/min.d.0.2 inch/min.

How long can a specimen remain to be viable for laboratory examination? What is the basis of this timing?

A swiming pool can be filled with water by two pipes in 12 hours. If a larger pipe takes less than the smaller pipe to fill the pool, find the time each pipe will take individually.

Take about 10 mL of distilled water (or rain water) and 10 mL ofhard water (from a tubewell or hand-pump) in separate test tubes.n Add a couple of drops of soap solution to both.n Shake the test tubes vigorously for an equal period of time andobserve the amount of foam formed.n In which test tube do you get more foam?n In which test tube do you observe a white curdy precipitate?

A tank can be filled with water by two pipes running together in 11 19 minutes. If thelarger pipe alone takes 5 minutes less to fill the tank than the smaller pipe, find the timethat each pipe will take to fill the tank.
