Un muchacho le dijo a otro. "adivina cuntos aos tengo si las dos terceras partes de ellos menos 1 es igual a mi edad actual menos 6". A hand dryer blows heated air downwards out of the exit duct at a velocity of 4 m/s. The temperature and density of the ambient air at the inlet are 15 C and 1.23 kg/m3, while at the outlet it has temperature 35 C and density 1.15 kg/m3 The blower power is 10.0 W and the heater power is 715 W. Consider the inlet to be at the large mass of ambient air which has negligible velocity. a) What is the pressure at the outlet? 4 m/s, 35 C b) You will be applying the energy equation. Why can you ignore any height differences in this situation? c) If the specific heat of air C-1000 J/(kg K), where -C T, find the change in internal energy per unit mass from the inlet to outlet. d) Find the mass flow rate through the dryer. e) What is the power loss in the system? f) What is the loss in the system? g) What is the head loss in the system? h) What is the total loss coefficient of the system, referred to the outlet velocity? i) If there were no heater, would the temperature of gas at the outlet be higher, the same, or lower than the inlet?

On a screen 17.5 cm from the grating, the third-order maximum of the shorter wavelength falls midway between the central maximum and the first side maximum for the longer wavelength. If the neighboring maxima of the longer wavelength are 8.44 mm apart on the screen, what are the wavelengths in the light On a school field trip, there will be one adult for every 12 students.
