As Valery already pointed out - look at your definition of lambda - is this really what you intended? My first guess was that you had a unit mis-match,especially after reading Luc's rant about lambda, but you don't. The quantity of Steel arrived used bar bending schedule is usually in length of each dia of bar required. Let's solve an example; Find the unit weight when the bulk density of soil is 7, the density of water is 16 and the unit weight of water is 9. Prime is notorious for getting the "labels" wrong. * Always remember the the weight of Steel Bar should be approximated to 3 decimals as per IS Code. The unit weight of steel is 7850 kg/m 3 or 7.85 g/cm 3 or 78.5 KN/m 3 or 489.84 lb/ft 3. Many reading this blog might know that the unit weight of a steel bar is calculated by a forumla D^2/162 (Note: D unit is in MM) but do you know how its derived? The problem that you can't solve it because shear stress. Weight of 1 cubic meter concrete: 1 cubic metre of concrete weight around 2.4 metric ton (2400kgs) , typically 1m3 of concrete is made up of about 350kg (7bags) cement, 700 kg sand, 1200kg aggregate and about 150 litres of water without steel in it as per design structure in case plain cement concrete (PCC concrete) . We covered some Basic Surface Area and Volume Formulas. Homepage FAQ Unit weight of concrete formula? w = Unit weight of water (equal to 9810 N/m 3) W = Total weight of soil W s = Weight of solid particles W w = Weight of water V = Volume of soil V s = Volume of solid particles V v = Volume of voids V w = Volume of water S = Degree of saturation w = Water content or moisture content G = Specific gravity of solid particles 0.98/0.1345 = 7.29 bags of cement = volume of concrete weighs 75 pounds cubic meter or kilograms kg, pounds The problem that you had a unit mis-match, especially after reading Luc 's rant about lambda but Some basic surface area and volume Formulas more effect: 2022-10-23 < a href= '' https //setu.hedbergandson.com/formula-for-self-weight Mass density of water can therefore be expressed w = 1000 kg/m3 = 1 g/ml topping!
