Consider an air solar collector that is 1 m wide and 5 m long and has a constant spacing of 3 cm between the glass cover and the collector plate as shown in Figure below, Air flows at an average temperature of 45°C at a rate of 0.15 m/s through the 1-m-wide edge of the collector along the 5-m-long passageway. Disregarding the entrance and roughness effects and the 90° bend, determine the pressure drop in the collector.
The pressure in a section of a horizontal pipe of diameter d1 = 2.0 cm is p1 = 142 kPa. The water flows through the pipe at a volumetric flow rate V = 2.8 L/s. If the pressure at a certain point is reduced to p2 = 42.6 kPa, due to a throttling of a pipe section, what should the diameter d2 of the throttling section be? Consider the density of water ρ = 1.0 g/cm3. Choose the correct option:

A 90" elbow is used to direct water flow at a rate of 0,025 m3/s in a horizontal pipe upward. The diameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local atmospheric pressure. The elevation difference betwoen the centers of the exit and the inlet of the elbow is 35 cm. The weight of the elbow and the water in it is considered to be negligible.

According to Torricelli´s theorem, the velocity of a fluid discharging through the hole of a reservoir is V=(2gh)^1/2, where h is the height of water above the hole, as shown in the figure. If the hole has a section Ao and the reservoir is cylindrical with a cross-section of area Ab>>Ao. Obtain a formula for the time it will take for the reservoir to completely empty if the initial height of the water is ho.
A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.
