Hematocrit A hematocrit is a test that measures the proportion of a person's blood that is made up of red blood cells (RBCs). Blood consists of RBCs, white blood cells (WBCs), and platelets suspended in a fluid portion called plasma.The hematocrit is a ratio of the volume of red blood cells to the volume of all these components together, called whole blood.The value is expressed as a percentage or fraction. For example, a hematocrit value of 40% means that there are 40 milliliters of red blood cells in 100 milliliters of blood.he hematocrit is a ratio of the volume of red blood cells to the volume of all these components together, called whole blood. The value is expressed as a percentage or fraction.

6 ft 2x6 beam - how much downward pull can it take? Two 2x6es on 24 intervals would support 40PSF (pounds per square foot) live load (i.e. load that comes and goes such as people and furniture) plus 10 PSF of dead load (weight of the structural elements) but we won't count the dead load allowance here because the 2x6 is still a part of the porch roof support.he weight of you suspended from the rings in the center of the joist is not exactly a uniform load but the formula is, again, for 8'-6 span, so the extra strength that the shorter span affords would even that out.

How Do I Choose the Correct Floor Joist Size? A better choice would be using a 2 x 10 (50.8 x 254 mm) joist size. Using grade 1 lumber will provide more structural support with a smaller joist size. Calculations for choosing a floor joist size depend on the grade and type of the lumber, the length of the span, and the joist spacing. In addition, the weight of both live and dead loads must be considered. A dead load refers to the weight of all the materials involved in the building or deck.

How To Build A Deck2 The load from the deck is transferred directly to the joist. The Joist are supported by the beams and ledger. Joist spacing is determined by the type of wood used, and the size of the joist itself. Common spacing (how far apart each joist is from the next) for decks are 16 inches, 24 inches or 32 inches on center. The span of the joist (how long a joist is between supports) is determined by the same factors.
