The Islamic University of Gaza, Instructor: Dr. Khalil M. Al Astal Civil Engineering Department, : Eng. Mohammed H El Nazli Fluid mechanics-Discussion, Eng. Sarah R Rostom First semester, 2016. Homework of chapter (1) (Solution). 1. A certain gasoline weights Ib/ft3 . What are its mass density ,Specific volume, and specific gravity ? Solution 2. A tank with dimensions of 3m length, 2m width, and height is filled with a liquid which have a specific gravity of the mass and weight of this fluid. Solution Vtank = Vliquid = 3 2 = 15m3 , liquid = 1000 = 2500Kg/m3 . Mliquid = Vliquid liquid = 15 2500 = 37,500 Kg Wliquid = 37,500 = 367875 N = KN . 3. Calculate density , specific weight , and weight of one litere of petrol of ( ) ? Solution petrol = 1000 = 700 Kg/m3 , Vpetrol = 1 liter = petrol = petrol g = 700 = 6867 N/m3.
