Air at 1.3 bar, 423 k and a velocity of 40 m/s enters a nozzle operating at steady state and expands adiabatically to the exit, where the pressure is 0.85 barand velocity is 307 m/s. for air modeled as an ideal gas with k= 1.4, determine for the nozzle (a) the temperature at the exit, in k, and (b) the isentropic nozzle efficiency.

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

i don’t know what the answer is i wish i

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
