At high altitudes, mountain climbers are unable to absorb a sufficient amount of o2 into their bloodstreams to maintain a high activity level. at a pressure of 1 bar, blood is typically 95% saturated with o2, but near 18,000 feet where the pressure is 0.50 bar, the corresponding degree of saturation is 71%. air contains 20.99\(\%\\) o2 by volume. assume that the density of blood is 998 kg m−3. find the mas.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
