How long will it take the water surface in the tank shown to drop from h = 3 m to h = 50 cm? **Problem 5.75: Valve Flow and Pressure Drop**The diagram illustrates a valve setup with the following components:- A stem connected to a disk, enclosed by a bonnet.- Packing material to ensure a tight seal.- A body that houses the valve's internal elements.- A seat against which the disk seals.- An opening for fluid flow.The problem involves estimating the pressure drop across the valve using the Bernoulli equation, given a 10-gpm flow of water at 60°F. The upstream pipe has an inside diameter of 1 inch. The distance across the seat is 1/8 inch, with the valve opening at 1/2 inch in diameter. **Problem 5.76: Flow Through an Orifice**An orifice flow situation involves a minimum area, "vena contracta," where the area ratio to the orifice is 0.64.Tasks:a. Derive a discharge equation using \( Q = C_d A_o (2 \Delta p / \rho)^{1/2} \), where \( A_o \) is the orifice area, and \( \Delta p \) is the pressure difference.Note: "psid" indicates differential pressure, not absolute or gauge.**Problem 5.78: Oxygen Leak**Oxygen leaks from a small orifice in a bottle. The scenario includes:- Bottle volume: 0.1 m³- Orifice diameter: 0.12 mm- Temperature: 18°C- Mass-flow rate: \( \dot{m} = 0.68 \, \text{Pa} / \sqrt{RT} \)Objective: Determine the time for pressure to drop from 10 to 5 MPa.**Problem 5.79: Water Surface Drop in Tank**A tank of 60 cm diameter and liquid height \( h \) is connected to a 3 cm diameter pipe. The equation for flow is \( V = \sqrt{2gh} \).Objective: Calculate the duration for water surface level to drop from 3 m to 50 cm.**Problem 5.80: Pressurized Tank Drainage**For a draining pressurized tank:- The exit velocity \( V_e \) is calculated as \( V_e = \sqrt{ \frac{2p}{\rho} + 2gh} \).These problems explore fluid mechanics concepts involving flow dynamics through valves,

Two ends of an U-tube manometer which contains mercury, is connected between two pipes (A & B) that carries oil of specific gravities 1.05 & 1 respectively. The center of the pipe B (right limb) is 14 cm above the pipe A (left limb). The mercury level difference in the Left limb is 4.2 cm, and the height of fluid in the left limb is 6.1cm, find the pressure difference between these two pipes in Pascal. Draw the diagram.
An oil of specific gravity 0.88 is flowing through the pipe of diameter 30cm. one end of the simple U tube manometer contains mercury, is inserted with the center of pipe and other end is open to atmosphere. The level difference in mercury is found in the right limb as 32 cm. The distance between the center of the pipe and the mercury level in right limb is 18 cm. Find the pressure of oil in the pipe in kPa. Draw the diagram neatly. (Enter only the values by referring the unit given.
