Compute the pressure difference between m and n, in pounds per square inch, when: a) Fluid A is brine (sp gr 1.15), the gage fluid is oil (sp gr 0.92), and z = 49.69 in.b) Fluid A is water, the gage fluid is air, and z = 19.69 in.

Need help with this engineering problem.

Q1: The density of oil is 850 kg/m³, and the dynamic viscosity is 5 x 103 kg/ms. Find: 1. Its relative density. 2. Kinematic viscosity 3. Write all properties in this question in MLT and FLT systems.

Please don't use chatgpt, strictly i need a handwritten solution.

The density of liquid water at 25 degrees celsius equals 62.2lbs/cube ft. Suppose the KD DF stud at the top of the page weighs 13.35lbs.  And suppose the KD DF stud is thrown into a swimming pool, Twater=25 degrees celsius. Based on data would the stud: sink completely, partually. or float completely

4. If the modulus of elasticity (E) for water is given to be 2.2GPa, what pressure is required to reduce the volume by 0.6%? 5. A tank contains two substance oil (A) and water (B) subject to variable air pressure: the dimension is shown below and corresponds to 1atm If air is
