I want the same solution, but with the mention of questions data and a detailed mathematical solution. 5-27. Blood flows from the left ventricle (LV) of the heart which has an exit diameter of di = 16 mm, through the stenotic aortic valve of diameter d, = 8 mm, and then into the aorta A having a diameter of dy = 20 mm. If the cardiac output is 4 liters per minute, the heart rate is 90 beats per minute, and each ejection of blood lasts 0.31 s, determine the pressure drop over the valve. Take p, = 1060 kg/m². LV SOLUTION The volume of blood pumped per heartbeat is 4 L/min 90 beat/min (0.0444 L/beat) 1m 1000 L - 44.44(10*) m²/beat Thus, the discharge of blood by LV is + 44.44( 10“) m²/beat 0.31 s/beat 0.1434(10-3) m²/s Then, the average velocities of the blood flow from the LV and into the Aorta; V¡ and V3, respectively are 0.1434(10) m²/s = V; [ #(0.008 m)* ] Vị = 0.7131 m/s 0.1434(10-3) m²/s = V3[ =(0.01 m)*] Q = V,A;; %3D %3D Q = V½A;: V3 = 0.4564 m/s Writing Bernoulli's equation between the two points, P V? + gz = 2 2 + gz3 Pb Pb Pi (0.7131 m/s)² P3 (0.4564 m/s)² + 0 = 1060 kg/m³ 2 1060 kg/m A, = P3 - Pi = 159 Pa Ans. %3D

In order to improve the production time, the supervisor of assembly lines for a manufacturer of cellular phones has studied the time that it takes to assemble certain parts of a phone at various stations. She measures the time that it takes to assemble a specific part by 158 people at different shifts on different days. The record of her study is organized and shown in the following table. Assume the normal distribution. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) Time That it takes a person to Assemble the Part (minutes) What is the mean (in minutes)? x = minutes What is the standard deviation (in minutes)? S= 157 Z = 4 5 6 7 8 9 10 minutes What is the z value corresponding to 6 minutes? X - X 6- =*=*=. S Frequency 13 24 26 32 26 24 13

Need help with the calculations i keep getting lost in the conversions

I want to briefly summarize what he is talking about and what you conclude.. the two graph pls urgent(ventilation system)
