Water flowing through a 10-cm-diameter water pipe at a rate of 0.1 m3/s. now a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water. the inlet side of the pipe is part of a continuous piping system( so that the pressure may not be atmospheric), but the outlet is discharging water to the atmosphere. disregarding the frictional effects, determine the force exerted on the bolts due to the water flow?

i saw many answers and they solve for bernoulli equation and they find the gage pressure to be positive and the final answer to be 1551n. and i solve for gage pressure to be negative and find the last answer to be 364.3 n

which one is correct?

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
