According to health.gov 1 in 4 adults in the United States have arthritis, leading to a disability. Healthy People 2030 is focused on reducing pain, disability and restriction of arthritis due it to becoming more common in the elderly population. Arthritis causes severe pain, half or not more people with arthritis have trouble with daily living activities and are unable to work. The plan of action is to help adults to manage pain by expanding physical activity, to reduce pain and hopefully disability. People with arthritis ae more prone to having other chronic diseases like heart disease, diabetes and being overweight. Recent data shows ages 18- 65 and over are more likely to develop arthritis or severe to moderate joint pain. Studies show select target was 52.1 percent on 18 years age and over as well. The baseline, according to Healthy People 2030 was 55.3 among the age group of 18 years and over, who were diagnosed with severe or moderate arthritis by providers.Arthritis is becoming more common in young Americans, due to diet changes, old injuries and poor activity. Implementing diet changes by putting alkaline foods in your daily diet such as Cucumbers, Apples, Cherries, Key Limes, Melons, Kale, Avocado, Okra, Quinoa, Onions, Agave, Dill and Walnuts. Low impact and calming exercises such yoga, walking and swimming could also be implemented. As well as cryotherapy, which also has many benefits for pain and inflammation as well.

Hi, I'm more interested in questions 4 & 5, could you please explain them in detail? Thanks. A 250 V shunt motor has an armature resistance of 0.4 Ω and runs at a speed of 750 rev min –1 when taking a full load current of 25 A. 1) Estimate the speed of the motor at no load when the armature current is 3 A, assuming that the flux per pole remains constant. 2) Derive the relationship between speed, emf and flux. 3) Calculate the field current for a field resistance of 110 Ω, if the load torque remains constant. 4) Calculate the new armature current if the speed is increased to 1000 rev min –1 5) Hence, find the value of the additional resistance required in the field circuit to maintain this current.

3. A certain obstruction-type flowmeter (orifice, venture, nozzle), shown in the figure below, is used to measure the flow of air at low velocities. $P_1, T_1$ Flow 2 1 The relation describing the flow rate is $\dot{m} = CA \left[\frac{2gP_1}{RT_1}\right]^{1/2} \Delta p$ Where C is an empirical-discharge coefficient, A is the flow area, $\Delta p$ is the pressure difference between $p_1$ (upstream pressure) and $p_2$ (downstream pressure), $T_1$ is the upstream temperature, g is the gravitational acceleration, and R is the gas constant for air. Calculate the uncertainty in the mass flow rate using the non-analytical and the analytical methods for the following uncertainties: C = 0.92 \pm 0.005 $p_1$ = 172,400 \pm 3500 Pa $\Delta p$ = 9,653 \pm 34.5 Pa A = 0.065 \pm 0.000065 $m^2$ $T_1$ = 38.9 \pm 1.1 K The rest of the parameters are: g = 9.81 $\frac{m}{s^2}$ R = 286 $\frac{J}{kg \cdot K}$ Hint: the mass flow rate is function of the following variables: $\dot{m}^* = f(C, A, p_1, \Delta p, T_1)$
