Expert Solution

When the blood pressure and blood volume is High , it is regulated by somany mechanism like neural regulation , hormonal regulation

when blood pressure and blood volume is high ------->increased glomerular filtrtaion Rate( It is due to the increased glomerular hydration pressure)------->Inhibit the release of Renin from the juxtaglomerular apparatus ---->increased excretion of the water and sodium.-------->inhibition of the release of Anti diuretic hormone (ADH) from the pituitary (Negative feedback mechanism )------->Blood pressure and blood volume is lowered to Normal

Another mechanism is by the help of Atrialnatriuretic factor(ANF)

High blood pressure nad high blood volume dilate the chambers of the Heart---->Increased release of Atrialnatriuretic factor(ANF)---->ANF act on the renal tubule ---->increased excretion of the sodium and water ------>Blood pressure and blood volume is lowered to Normal

There has been a lot of interest about replacing gasoline with ethanol, but is this really a good idea? We’re going to compare a blend of ethanol (70% ethanol and 30% gasoline by volume) to gasoline. Calculate the lower heating value (LHV) of a 70% ethanol/30% isooctane mixture in terms of kJ/mol of fuel. Assume complete combustion. How does this compare to the tabulated value for gasoline (isooctane)? Assuming a 20% thermal efficiency, if you need to get 100 kW...
