The flash point of an engine oil is 363 degree F. What is the flash-point temper

Question

The flash point of an engine oil is 363 degree F. What is the flash-point temperature in K and R? The pressure in a water line is 1500 kPa. What is the line pressure in lb/ft^2 units and lbf/in^2 (psi) units? Determine the atmospheric pressure at a location where the barometric reading is 750 mm Hg. Take the density of mercury to be 13,600 kg/m^3. The water in a tank is pressurized by air, and the pressure is measured by a multi fluid manometer as shown in Fig. P1-53. Determine the gage pressure of air in the tank if h_1 = 0.2 m, h_2 = 0.3 m, and h_3 = 0.46 m. Take the densities of water, oil, and mercury to be 1000 kg/m^3, 850 kg/m^3, and 13,600 kg/m^3, respectively.

Explanation / Answer

1 Ans -

   F = (9/5) *C +32

so at 363 deg F ,

deg C will be = 183.88 deg c

so in terms of kelvin K, it will be equal to 273.15+ 183.88 = 457.03 k

In terms of R,

R= 822.67

Q 2 ANS-

water line pressure = 1500 kpa given

1 kpa= 20.885 lb/ft2

so 1500 kpa =31328.16 lb/ft2

= 1500000 N/m2 =0.145037738*1500 lbf/in2= 217.5566 lbf/in2

Q 3 Ans-

p= rho* g* h

= 13.6*1000*9.81*750*10-3 = 1.00062 kg-m/s2 = 1.00062 pa answer
