The flow rate of a Newtonian fluid is found to be proportional to the square root of the supply pressure. By what percentage must the supply pressure be increased to increase the flow rate of a Newtonian fluid by 25%
Answers: 1
where P is pressure and Q is flow rate and k is a constant of proportionality. Ignoring k
![P_1=Q_1^{2}[\tex] then when flow rate is increased by 25% to mean 1.25 then [tex]P_2=(1.25Q_1)^{2}=1.5625Q_1^{2}](/tpl/images/0546/0489/ba128.png)
then the differences in these two pressures expressed as a percentage will be

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
