Will it carry 200 oak planks measuring 30 cm, 4 m, and 30 mm at a time if the weight of 1 dm³ of oak wood is 0.7 kg? How many kg of paint do you need to buy to paint a 1.5m high cylinder-shaped rainwater cover with a 0.7m radius? We paint the barrel from the outside and inside, and 100 grams of paint is needed to paint 1 square meter. Calculate the volume, radius, and surface if the iron's density is h = 7.6g/cm³. Determine its weight in kg if the density of the concrete is 2545 kg/m 3 The concrete hatch for a round well has a diameter of 1300 mm and a thickness of 80 mm. Material of density of 1189 kg/m³ occupies a container volume of 64 cm³. What is the weight of a granite ball with a radius of 60 cm if 1 m³ of granite weighs 2.7 tons? The model is made from exactly the same material as the original no numbers need to be rounded. How high is the model of the tower's weight of 1 kg? (State the result in centimeters). The tower's height is 300 meters, and its weight is 8000 tons. How many liters of water will drain if we dispose of the freezer? A layer of ice 23 mm thick was formed on the freezer's inner walls (and on the opening). The freezer has the shape of a cuboid with internal dimensions of 12 cm, 10 cm, and 30 cm. Determine the pressure difference above and below the plane's wing if the top of the plane is 10% longer than the bot What is the weight of a granite cube with an edge length of 75 cm if one m³ of granite weighs 2.7 tons?Īn airplane flies at a speed of 920 km/h at an altitude of 11 km above the surface of the Earth, where the air density is p = 0.36 kg/m³. specific heat capacity at constant pressure (J kg1 Krl) c, specific. How many kg of grass seed should be bought to establish a lawn around a circular fountain with a diameter of 5 m if the lawn is to be 1.5 m wide and 1 g of grass seed is used per 1 dm of the square area? water interaction dynamics from non-explosive passive cooling to supersonic. You can make ads in the Engineering ToolBox more useful to you Densities, molecular weight and chemical formulas of some common gases can be found in the table below: 1) NTP - Normal Temperature and Pressure - is defined as 20oC (293.15 K, 68oF) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr) 2) STP - Standard. Calculate the volume of the wooden prism. The wooden prism weighs 5 kg and has a density of 700 kg/m³. What is the plate thickness if 1 m³ weighs 8732 kg? The copper plate has a length of 2.2 m, width 92 cm, and weighs 5.6 kg. How much does a gold bar weigh 25cm, 8cm, and 37mm? The basic SI density unit is kg/m 3Ĭonversion of a density unit in word math problems and questions The formula is ρ = m/V, where m = mass and V is volume. Thermodynamic properties of heavy water - D 2 O. Density is defined as mass divided by volume. Heavy water ( deuterium oxide, 2 H 2 O, D 2 O ) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium ( heavy hydrogen 2 H D), rather than the common hydrogen-1 isotope ( 1 H H protium) that makes up most of the hydrogen in normal water. density, kgl Time constant of storage tank during the loading period, minute. The symbol for density is ρ (Greek letter rho). water temperature in a storage tank at time t, C TSto,m,t0 Mean water. The density (the volumetric mass density, specific mass) of a substance is its mass per unit volume.
