柴油密度多少是标准的?多少才算好的?

1000kg ÷ 0.85kg/L=1176.5L
7350 ÷ 1176.5 =6.25元/升

柴油密度是0.84千克/立方米?错了吧 是0.84千克/立方分米吧
0.84*1＝0.84千克(一升=一立方分米）

1.250L=250dm³=0.25m³m实=pv=0.85×10³kg/m³×0.25m³=212.5kgm用=0.8kg×250亩=200kg∵212.5kg＞200kg∴一箱油够用2.umg=fu*1000=40u=0.04F=500500=0.04*1000+0.04*NN=460/0.04=11500N货物...

1、密度的公式 ：ρ＝m/V (ρ表示密度、m表示质量、 V表示体积)
2、1t=1000Kg
3、根据公式一算：最后得出体积最大流量是 583.37m³/h

解题思路：（1）由密度公式ρ=[m/V]可知要测量柴油的密度，需测柴油的质量和体积，质量可以用瓶子装满柴油的总质量减去空瓶子的质量求出；
（2）柴油的体积，可以借助空瓶、水来间接得出，根据实验中的瓶子装满水的总质量减去空瓶子的质量求出瓶子装的水的质量，利用公式ρ=[m/V]算出瓶子的容积，再用柴油的质量和瓶子容积得柴油密度．

（1）因为瓶子中装满水和柴油时，柴油的体积等于水的体积，故可以通过计算水的体积来间接求出柴油的体积，所以步骤“④用量筒测出矿泉水瓶中所盛柴油的体积V”可以省略；
（2）矿泉水瓶中的水的质量m_水=m₂-m₁，
瓶子中柴油的体积V_柴油=V_水=
m水
ρ水=
m2−m1
ρ水
瓶子中柴油的质量m_柴油=m₃-m₁
柴油的密度ρ_柴油=
m柴油
V柴油=
m3−m1

m2−m1
ρ水=
m3−m1
m2−m1×ρ_水
故答案为：④；
m3−m1
m2−m1×ρ_水

点评：
本题考点： 液体密度的测量．

考点点评： 此题是一种间接测量物质密度的题型，实验中注意瓶子中倒水或柴油时一定要装满，目的是保证水和柴油的体积相同；同时也考查了应用物理知识解决实际问题的能力，是对密度测量的进一步理解．

简单了 先化单位,再根据质量等于密度乘以体积就可以,

还在跪求啊.好吧好吧
我按标准给你来一个吧.先算 封头 碟型 H＝505,V＝1.51
罐体筒部长度 7000-505-505＝5.99m 罐筒容积＝27.08
总容＝27.08+1.51+1.51 ＝30.1
容积表如下：

1.柴油的密度和温度有关,温度低时密度大.
2.一般来说,密度大说明柴油含有重组分烃类较多,燃烧值就比较高.简单地说,就是提供同样的热量时,需要的柴油少,或者说,同样一箱油,密度大时,车可以跑得远一些.
3.密度大的柴油,蜡点也高,低温时容易失去流动性,更不适合于低温地区.
