A nozzle with a radius of 0.250 cm is attached to a garden hose with a radius of 0.700 cm. The velocity of the water in the hose is 1.90 m/s and the velocity of the water in the nozzle is 14.9 m/s Required:
a. Calculate the maximum height to which water could be squirted if it emerges from the nozzle.
b. Calculate the maximum height to which water could be squirted if it emerges with the nozzle removed, assuming the same flow rate.

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i. e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?
