In medical literatures, local blood perfusion rate is typically presented as xx ml/(min 100g tissue), in another word, it represents xx ml of blood supplied to a tissue mass of 100 g per minute to satisfy its nutritional needs. As we learned from the course lectures, the local blood perfusion rate appearing in the Pennes bioheat equation is in a unit of 1/s, or can be interpreted as xx ml of blood supplied to a tissue volume of 1 ml per second. The following lists the blood perfusion rates in various organs or structures in a human body from medical textbooks: brain (50 ml/(min 100g tissue)), kidney (35 ml/(min 100g tissue)), and muscle at rest (3 ml/(min 100g tissue)). Please convert the above local blood perfusion rates into values with the unit of 1/s, therefore, they can be used in the Pennes bioheat equation. The tissue density in a human body is 1050 kg/m³.

The following processes occurs in a reversible thermodynamic cycle:   1-2: Reversible polytropic compression at pressure [X] bar at volume [Y] m3 to a pressure [Z] bar and specific volume [A] m3/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure [B] bar. 3-1: Reversible cooling at constant volume to the initial state. What are the final attempt values of X, Y, Z, A and B from the Part A of the eThuto Assessment. calculated formula similar question? X=       ; Y=     ; Z=       ; A=     ; B=

Atmospheric pressure can be reported in several ways. At sea level the average atmospheric pressure is 15 lbs/sq in, or 101.3 kPa, or 760 mm Hg, or 1 atmosphere. Since all of these are equal, you can easily convert from one to the other. For example, if your tire pressure is 32.0 lbs/square inch, you can determine the kilopascals in the following manner: 32.0 lb/sq in X 101.3 kPa / 15 lbs/sq in = 216 kPa. Now, find the pressure in mm Hg of a container that has a pressure of 9.92 atm. mm Hg

Density is defined as mass per unit volume (Fig. 1-25). Density: (kg/m) (1-4) The reciprocal of density is the specific volume v, which is defined as vol- ume per unit mass. That is, (1-5) For a differential volume element of mass ôm and volume &V, density can be expressed as P The density of a substance, in general, depends on temperature and pres- sure. The density of most gases is proportional to pressure and inversely proportional to temperature. Liquids and solids, on the other hand, are essentially incompressible substances, and the variation of their density with pressure is usually negligible. At 20°C, for example, the density of water changes from 998 kg/m' at I atm to 1003 kg/m' at 100 atm, a change of just 0.5 percent. The density of liquids and solids depends more strongly on temperature than it does on pressure. At I atm, for example, the density of water changes from 998 kg/m at 20°C to 975 kg/m at 75 C, a change of 2.3 percent, which can still be neglected in many…

Thermal conductivity k is a measure of the ability of a material to conduct heat. For conduction heat transfer in the x-direction through a surface normal to the x-direction, Fourier’s law of heat conduction is expressed as: Q=-kA.dT/dx   where ?̇ is the rate of heat transfer and A is the area normal to the direction of heat transfer. Determine the primary dimensions of thermal conductivity (k). Look up a value of k and verify that its SI units are consistent with your result. Write a set of primary SI units for k.

The gravitational constant g is 9.807 m/s² at sea level, but it decreases as you go up in elevation. A useful equation for this decrease In g is g= a - bz, where z is the elevation above sea level, a = 9.807 m/s², and b=3.32 x 10-61/s². An astronaut "weighs" 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z=325 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel Immediately after the satellite stopped moving? The person's weight in N while floating around in the International Space Station Is The astronaut feels a gravitational acceleration of m/s² N.
