Problem 3 Bi As shown in the figure below, a weight (0.225 m³) is added to the top of the piston (5 kg); both the added weight and the piston adds pressure to the oil (SG = 0.85) in a circular tank. The tank has a diameter (D₁) of 0.6 m. The oil in the tank has a height (h₁) of 1 m. An open-end pipe is connected to the oil tank from the bottom of the tank. The oil surface in the pipe is 1.5 m (h₂) above the oil surface in the tank. What is the density of the weight? Weight Piston hi W D₁ Oil

Suppose a Venturi tube (placed in the horizontal position of Pipe BC in Figure 1) from the right (Fig.2). The radius of the wide part of the tube is 5.0 cm; the radius of the thin part of the tube is 2.5 cm. The tube of shape U is filled with the mercury of the density 13600 kg/m . Determine what heightdifference will be stabilized between the surfaces of the mercury in U-tube. Ignore the losses.
A U-tube of uniform cross-section has both arms open to the atmosphere. The U-tube contains three immiscible liquids, with density PA, PB, and pc, as depicted in the diagram below, where po is the atmospheric pressure. We denote h to be the depth of the open surface of liquid A on the left arm, relative to the open surface of liquid Con the right arm. I is the depth of the interface between liquid B and C on the right arm and 2l is the depth of the interface between liquid A and liquid B on the right arm. Po PA (c) Po PC PB е е (a) Explain why the liquid densities need to satisfy the condition PA PB PC. (b) Write down an expression for the pressure at depth z below the surface of liquid A in the left-hand part of the tube. Show that l < h < 2l if PB + PC < PA•
The initial pressures at A and B are the same at 105 kPa. If the pressure at the liquid at A (SG1 = 1.96) is increased to 132 kPa while keeping the pressure at B constant, determine the new position (Δh, in mm.) of the mercury meniscus inside the tube as shown. Assume no change in the liquid densities. The connecting tube is a 1-cm in diameter, Y1 = 0.58 cm., and the inclination of the tube is 11° with respect to the horizontal. Assume unit weight of air to be negligible. Round off to three decimal places.

Air in a room at T0 = 290 K and P0 = 90 kPa is to be drawn by a vacuum pump through a 3-cm-diameter, 2-m-long adiabatic tube equipped with a converging nozzle at the inlet. The flow in the nozzle section can be approximated as isentropic. The static pressure is measured to be 87 kPa at the tube inlet and 55 kPa at the tube exit. Determine the mass flow rate of air through the duct, the air velocity at the duct exit, and the average friction factor for the duct.
